In the first part we will present the background and objectives of our project and we completed the review of the literature and Plan of Action was adopted. Then there are the details of the electronic system on board the robot. Finally, let us comment on the work done this year, both hardware and software.
1 Project Overview
1.1 Project Background
The robot is powered by two batteries( Dell Studio 1537 battery ,Asus Eee PC battery)Promocoes to electronics and the other the power to administer the section. They allow you to be independent. After prolonged use, the batteries must be recharged. The purpose of the "management and recharge the batteries" project is to be able to recharge the batteries again without human intervention. At any time, should the measured height of the two batteries and hierarchy.
When the threshold is evaluated by their supervisors, responsible for about 20% of the maximum load, the supervisor, the robot to its source for a full charge.
This fee will be non-contact, the robot will be positioned on the source and call the power required by an electromagnetic field. The fundamental question of power SONY VAIO VGN-AR830E battery, if and only if the robot is properly positioned. After the download is complete, the database stop the transmission of power. The information marked "battery" will be released to the supervisor.
1.2 Problems
The stakes are very clairs.il project is to understand how the individual cards, edit them as needed and to design and implement the program on the PIC board.
It is very important to prepare a complete file on the Dell Studio 17 battery electronic system to facilitate the resumption of the project next year. In fact, no precise and complete documentation we received. We believe it is important to fill this gap. The final challenge of this project is at a level of performance, how the robot works perfectly achieved.
1.3 Features
From the perspective of software development functions:
Management and the sequence of robot
Optimal control of battery charge
Recharge the batteries
The connection between the PC and the PIC
We have the opportunity to talk in more detail below each of these functions this report.
1.4 Quality of service expected in the status of the project, when we started, we will be satisfied if the majority of circuit boards, which is managed by the microcontroller. We focus especially this year to upgrade the Toshiba PA3399U-1BRS battery system hardware, the development of a draft documentation, and software to facilitate the acquisition of these prospective students next year.
1.5 Limitations
The project is innovative in nature, born a few limitations. We have goals, but if they are affected by other technological improvements possible. Our main disadvantage is the time we spend on the project.
2 Theoretical study
2.1 Robot Promoções
The robot, which goes from Promoções two batteries, electronic document management and the other food. They allow you to be independent.
After prolonged use, the batteries must be recharged.
The purpose of the "management and recharge the batteries(Dell Studio 1735 battery)" project is to two batteries for free without any human intervention.
At any time the level of both batteries are measured and sent Supervisor. When the critical level is assessed by supervisors, about 20% of its maximum load, the supervisor to move the robot to its source
for a full charge. This fee will be non-contact, the robot will be positioned above the Source and call the power required by an electromagnetic field. The fundamental question of power, if and only if the robot is properly positioned.
After the download is complete, the database stop the transmission of Dell Studio 1737 battery power. Information with the word "battery" the supervisor will be released. Our only regret is that no precise documentation of each card was provided. In fact, not an electrician. We had some difficulties understand how each card by card schemes. A major task of understanding was made. the resumption of aid Project, and we have documents, popular writings Please find attached.
In summary, we have:
Routing and size paper PROTEUS
Active components of the card,
Passive components map
The technical details of the microcontroller, 10
2.2 Overview of the PIC 16F877
Student choice was the PIC16F877 microcontroller from Microchip, for several reasons. After a thorough review of the literature, we have been waiting for this decision. In fact, the PIC16F877 is part of the family of microcontrollers Microchip PIC 16F that Dell XPS M1530 battery energy management can be an optimal control. 16F877 model that can be taken into account for a relatively high clock frequency of 40MHz, is ideally suited for applications where performance and energy is crucial. Relatively easy to use, this device offers a cost effective solution for so-called intelligent systems with very little equipment, as is the case for our project.
The PIC 18F877 has the merit of a conventional microcontroller (counters, PWM module, ...) and some specific characteristics. Of these, we retain the following items, which are particularly interesting in the context of this project and to confirm the selection with the microcontroller:
25 O are available
The complete electrical installation, which includes a large number of cards you must have enough ports I / O and control of each of the interlocutors. Universal Asynchronous Receiver Transmitter USART synchrnous Module This module can be used in a full duplex asynchronous system that can communicate with devices such as ordinateur.la with a PC SONY VGP-BPL13 can be configured to be a feature of the development and will be achieved through this form.
EEPROM data memory of 256 bytes
During the race turns its parameters can be stored in this memory dynamically and without the use of an external add-on (eg RAM).
In addition, the development and manufacture of embedded software on a PIC 18F877 thank you relatively comfortable, with a micro chip poisoning of a free C compiler and development 11
2.3 The software used
From the outset, we must develop the program, this robot in a comfortable and be able to offer a fast implementation. Use of Microchip MPLAB C18 compiler. And "libraries and PIC18F877.ce compiler for microcontroller family optimized features we can use the devices in the PIC (USART, ...) from a high-level programming.
MPLAB IDE (version V8.36) from Microchip is the development environment on which the system can be achieved. MPLAB C18 compiler is integrated into the environment. This free software includes a simulator that is useful to make and debug a program before loading the PIC.
Map Battery Management
The measurement of SONY VGP-BPS13/B battery voltage, circuit switching has worked in recent years have been preserved. Formatting is done by applying a voltage doubler in our case, get to linearize the voltage. Current measurement for its changes. Indeed, the LEM can not be 100% in the presence of electromagnetic fields, why not replace ACS712 Low, a least element, cheaper and works great for use in harsh environments.
Paper or paper-source inverter
We opted for the inverter transistors based on the parties, capacitors and diodes to keep, instead of an inverter on the market. In fact, this inverter M. Hamzaoui approved last year and is able to transmit Dell XPS M1330 battery power around 200W rated well above our expectations on the 70W. The settings of the frequency and the cycle will be led by a multi-turn potentiometer for better position and transfer of information precision.Les phototransistors with different wavelengths in order to avoid problems. The antenna and phototransistors are mounted at a distance from the main board
The technology chosen
This project is an extension of work done in recent years. We had to make decisions, to keep what works, consider possible improvements, despite a fairly sudden lower back.
Code
The entire project will be written in C in MPLAB.
Unit testing
They will review a comprehensive program to test whether the data from paper, cardboard and use of the UPS battery is recovering well.
It is simulated error carefully review all the cases possible.
Integration testing is a good agreement between the maps, and others, you should check that the level of both batteries properly sent to the supervisor bus.
Indicators of achievement
The following review of the project's success:
The delivery of all components of the two plates, Detection of IR LEDs and photo transistors Accurate current measurement, The data received by the microcontroller, Efficient transfer of power between the two maps, A battery Dell Vostro 1510 battery to need (below), Stop the transfer of energy when it is loaded, Communication bus.
Matrix IADT
This matrix is used to validate the specifications. Part of this inspection is a visual inspection of the operation. You should pay particular attention to: "PWM" flash LED displays on the map, the switching of the inverter, For LEDs for RX and TX of the series connection of two cards, LED for battery (Dell Inspiron Mini 12 battery)charging, A good connection between the antennas.
It is a study in detail: Program with bug fixes, Cards proper consideration of the welds, good contacts, the absence of a short circuit.C Demonstration The demonstration, the media operation is based on: Operational communication between the card and battery management.
Higher
The transmission and reception of energy Good battery life.
These are the points to test the event. List of equipment:
For this project, we are the conventional devices (PC HP Pavilion DV5000, solder, multimeter, ...) should To deal with the programming and use of the PIC 18F877, we used a test disc, this type of pad is very well suited for an experimental phase.
Technical Data
As part of our project is to generate the magnetic field around the battery(Asus A32-F3 battery) to recharge. This register has been done previously. The function is added to the order, the action begins or complete the process.
In addition, you should think about the selection of components, including power transistors. Currently, the quality of the transistors, the output current is limited to 8 A

Induction and resonance for VE
Hello, today's New Economy ", to solve a current Asus Eee PC 900 battery problem:. Electric Vehicle In this first part we will consider charging systems, especially the new wireless technologies.
In its recent Green Paper on infrastructure charging for public vehicles without emitting carbon, "Louis Black, Senator of the Alpes Maritimes and several co-ordinator, said:
"In 2013, virtually every automaker in the world, one or more models of vehicles batteries. In France, the first quarter of 2010 is sold. This new generation of vehicles is by developing technologies and new batteries more stable performance and Asus Eee PC battery technical higher (autonomy, lack of memory effect, etc.) .. "
In support of this, the development of charging solutions (equipment and infrastructure) soon became a major problem that both automakers that the authorities will be integrated. One of the most important issues for users of electric vehicles is the battery life: "As far I can go before having to recharge my Dell Studio 1537 battery?".
In the area of workshop equipment and infrastructure are two opposing philosophies: the burden of "wire" or charge "wireless". Each technology has its advantages, including loading wireless to get rid of loose wires and simplify loading.
In this article, single process, the wireless recharging of groundwater, to bring hope to facilitate the recharging of electric vehicles.
A little 'history
The technology to transmit electricity without direct contact is not new. In 1836, Nicholas Joseph Callan was the first attempt. The set consists of two single coils (called primary and secondary) positioned around an iron core. In the short term combines a primary battery SONY VGP-BPS2 battery, which induces a voltage in the secondary causing a spark.
Since then, the process, something democratized and is used in medical implants, as well as everyday objects, such as electric toothbrushes and cell phones. Experiments for recharging electric vehicles is actually carried out in 90 years.
Two competing technologies for wireless charging
Today, two competing technologies: the transmission of energy through inductive coupling of electromagnetic coupling resonance energy transfer. Let's look at what it is.
The electromagnetic coupling
The system consists of two sensors: a transmitter (device) connected to the mains and a receiver (to charge the device), along with the battery,Dell Studio 1735 battery.
When a current in the transmitter, a magnetic field induces an electric current in the receiver that the battery is recharged.
However, this method has one major flaw: the transmitter and receiver must be perfectly aligned and close together, the magnetic field strength increases in proportion to the square of the distance.
Resonant inductive coupling
This new method of wireless energy transfer called WiTricity, suitcase word for "wireless electricity" was conceived by Dave Gerding in 2005 and identified in 2007 by a team of Massachusetts Institute of Technology (MIT) by Dell Vostro A840 battery Professor Marin Soljacic.
Two copper coils 60 cm in diameter, with a resonance of 10 MHz, one plugged into a 60-watt bulb, and a power source two meters away and lit the lamp with a yield of 40%, even if the two objects were in line of sight.
The operating principle is similar to that of a transformer "plane", the transmission coil (transmitter) is equipped with electricity Dell Latitude D830 battery, which generates a magnetic field. Created under the influence of this magnetic field induces a current in the receiver coil (receiver). The fact that the two coils are granted on the same frequency creates a resonance phenomenon, the effect of increasing the distance that the magnetic coupling can be transmitted is.
Resonance transfer of energy technologies that enables the efficient transfer of energy at much greater distances, and preliminary alignment of the traditional site parking induction. In addition, the transmission power Dell XPS M1330 battery is only slightly disturbed by the presence of objects between the coils, and is not harmful to the environment.
This brings greater flexibility, the device can be inserted into the soil and are resistant to the elements (rain, snow, ice ...).
Experiments have already made the charge without wires
Praxiteles
The experiment in Saint Quentin en Yvelines, which lasted from October 1997 July 1999 began to provide users with a fleet of electric vehicles Renault Clio self-service.
For this experiment, Dassault Electronique and EDF have developed and tested a wireless system of charging by induction.
Electric buses in Turin and Genoa
In 90 years if the New Zealand society HaloIPT the cities of Turin and Genoa, Italy, a forty-bus wireless system with resonance charging. These buses are still in use and load resonant system
Google / Evatran
On campus in Mountain View, Google provides its employees with a fleet of electric vehicles that can recharge mobile phones, "the Plugless power" of the company Evatran.
Wireless resonant charge and developed across the Atlantic!
The main market
The products currently offered load on the wireless market has characteristics similar to cable systems. The powerToshiba PA3399U-1BRS battery is in the order of 3 kVA to transfer a full charge in about 8 hours (standard load). The economy must be the Chargers' no child a similar price to the cable carriers.
WiTricity (www.witricity.com)
The company was founded in 2007 sold the inductive coupling technology transfer resonance energy, developed and tested by professor Marin Soljacic, heads a research group at MIT. In 2010, Delphi Automotive and WiTricity an agreement on wireless charging systems for electric HP Pavilion DV7 battery and hybrid vehicles are expected to develop.
Recently, in April 2011, Toyota Motor Corporation (TMC), a technological collaboration with WiTricity to implement and promote the use of wireless systems to recharge the batteries of hybrid vehicles the company. TMC intends to share in WiTricity Corp.
The company develops and sells New Zealand complete systems for charging Dell Precision M4500 battery wireless adaptable to any type of vehicle. The system is compatible with the network of the vehicle, which means that it is reversible, and the vehicle to inject the energy of the battery in the network. Hopefully, it would be smart grid technology, then, with electric vehicles is coupled to renewable energy Dell Precision M4400 battery.
A subsidiary of MTC American transformer (transformer manufacturer), Evatran, founded in 2009, sells "Plugless Power", a wireless charging system. The company is testing Google "Power Plugless" size is based on its headquarters in Silicon Valley.
Indisputable advantages and practical applications for wireless charging We have seen the wireless charging offers many advantages:
No contact between the loader and the vehicle is not a thread to remember to connect (or disconnect)
Sensors embedded in the parking lot of the soil or groundwater and less visual impact on the environment.
Insensitive to weather (rain, snow, ice), as well as dust and chemicals to make available in any environment (parks, industrial areas ..).
The transfer of energy today when a vehicle is parked in the river, so no risk to human safety.
The SONY VGP-BPS9/B battery resonance technology, the advantages of electromagnetic induction are undoubtedly the way forward, even if it is a way to achieve returns of more than 80%.
Shop Wireless certainly has a great future for themselves if they develop are of course linked to the possibility of allowing consumers a convenient cable without a solution, but cheaper than free. Finally, the wireless charging is by induction or response to solve the problems caused by the presence of wires placed in the street and optimize Dell Vostro 1510 battery charging of electric vehicles.
The technology also opens the way for the resonant load "continuous". What is it? A lane reserved for electric vehicles is created, where sensors are embedded in the road at regular intervals. The transfer starts, the vehicle is the energy Pavilion DV5000 battery that can continuously charge the battery.
Reload wireless seems to have a future, provided that the effects on safety and health are not given a hard time in the long run!

Computer security (I)
Everyone knows the Internet is the hunting ground of pirates (hackers), and the prey of evil viruses, spyware (spyware) and spam others. Faced with serious consequences that their actions can be triggered for a company, all these Dell Inspiron 1525 battery forms of activities as crimes and punishment as such. We'll be back.
All Internet users who have been or may one day become a victim of the acts of these criminals, we will focus in this article on the operation and methods of protection against viruses, phishing, spam, spyware and other "social engineering". To avoid this article, we will detail the risks and threats to our IT infrastructure, system vulnerabilities and software and how it protects HP Pavilion ZD7000 battery itself in the article on the prevention of hacker attacks.
Virus
All the risks that threaten the security of our computer, the virus is the most common. What is a computer virus? This is an unwanted program that installs on your computer without your knowledge. Lines of instructions telling him how to act, to multiply and infect other programs and other computers.HP Pavilion DV2000 battery
As stated by Microsoft, a computer virus is a program of a few kilobytes. Worms like Slammer (aka Sapphire) are only 400 bytes.
Windows, a fertile environment for viruses
Note that once the prerogative of the environment of Windows virus has always been the main target of virus writers. In fact, you almost never have a virus or spyware related in environments such as Unix and Mac OS X or Linux. Why?
These are the operating system manages computer HP Pavilion DV9000 virus, do not take the hardware platform, Intel or PPC Mac, for example. So the fact, do not install an Intel CPU in a Mac to make it more susceptible to viruses and other malicious actions.
The security model of Unix Mac OS X will be assumed by default designed to protect the system against threats to platforms other rule. We can say that Mac OS X since the beginning,SONY VAIO VGN-AR830E battery was designed with safety in mind, knowing that the "zero risk" does not exist.
And in fact, there are some viruses that attack Mac, as "proof of concept" test virus as "OSX.Macarena" but they are not really there to destroy (their virulence your installation directory is limited, and they easily melted), but Dell Inspiron 5100 battery designers who can demonstrate environmental pollution.
It is, as Kaspersky, said in a report, not on Mac OS X is immune against the virus, only better protected against attacks. As proof, the end of 2007, the first Trojan (OSX.RSPlug.A) Apple has addressed and explained in this article. Now he can qualify for the security of Mac OS X. Stay tuned.
However, it is not the idea of installing a Windows partition on your Apple for example (via BootCamp), it would again open up your system for SONY VAIO VGN-FW350DH battery viruses and spyware.
Note that your system is just as vulnerable, if you have a virtualization software such as "Parallels Desktop" or another solution "Virtual PC for Mac" to use to create a Windows virtual machine on Mac OS X. However, Mac OS X partition will be protected forever.
Note that this attack very few viruses that can run multiple operating systems despite the differences inherent in any software architecture. This is the case of the virus "Bi.a" written in assembly language, which operate both Windows and Linux. But even here there is only a "proof of concept" not really malicious viruses. However, after Kaspersky and SANS, in the future more and more viruses of this strain to become virulent. This has already been infected with virus beam, Windows PCs and PDAs launched in February 2006. In short, no Toshiba PA3285U-3BRS battery platform is invulnerable, but some more than others ...
This vulnerability in the Windows environment and the price for some innate wide licenses, why in the space of a generation (1981-2007), he had a monopoly, Microsoft has seen its market share, reduced to less than 40 % in favor of Unix, Linux and other Mac OS X. At each of the lesson.
This clarification takes place, to describe in detail the functionality of any computer Toshiba PA3465U-1BRS battery viruses and how to eliminate them.
Evolution
Dozens of new viruses are spread daily on the Internet, especially from the new republics of Eastern Europe, whose population is likely to be unemployed, but skilled Toshiba Satellite A10 battery and Western Europe (France, Southern England, Flanders, the Netherlands), the United States and the Far East.
In 1990, he was given 200-500 viruses under DOS with an average increase of 0.6 virus / day. Since then, the number of viruses has doubled every year with an acceleration of 1992. In the year 1996 exceeds the threshold of 10 000 virus. In 2000, there were 50,000 viruses.
List of viruses Kaspersky Today, almost 550,000 and 213,193 signatures. The software "NanoScan" Panda is able to identify more than one million signatures!
You can now ask whether the two anti-virus is as complete as the other, knowing that one has twice as many signatures as his opponent? The answer is "yes, probably" because it must be a comparison to be sure. We'll be back.
In fact, some Toshiba PA3107U-1BRS battery companies create a single signature virus, but it identifies many forms of viruses. So arbeitet and Kaspersky. In fact, transfer some worms (worms) and come in more than 400 varieties, as are many additional signatures! These polymorphic as "whales", a virus just 10 KB in 33 existing variants. In addition, a competitor for reasons of strategic business practices or as to create as many signatures as viruses and mutants, the total of an impressive number of signatures that can actually be two to five times higher than will be giving its competitors.
Also note that the virus is like nothing Kaspersky Virus List of encyclopedias encyclopedic list and make a small fraction of all existing viruses. Your best source of information are also Toshiba PA3399U-1BRS battery forums. We'll be back.
The elimination of viruses and other malware is an ongoing battle, as long as there are computer criminals will take. It is not for nothing that McAffee has chosen this name have you ever noticed that it means "make a fresh" subscribe, in other words, you buy our anti-virus software. In fact, the daily update ...
In November 1991, David M. Chess High Integrity HP Pavilion DV5000 battery Computing Laboratory IBM reported in the "Virus Bulletin" newspaper, about 30 viruses that were responsible for attacks around the world. Today they are the work of about 180 viruses, as explained WildList Observatory, which monitors the activity of the virus via the Internet.
Types of viruses
Are grouped into five major viral families. Boot virus in the boot sector of a hard disk that is read when the computer HP Pavilion ZT3000 starts to hide. These viruses replace the boot sector with a copy of itself and again the region of origin to another part of the disk. It goes without saying that even after formatting the hard drive, they are still there!
Then came the large family of viruses, the application executable (. Exe,. Com,. Sys. Inf. Dll. Vbs, etc) to infect. They replace the startup file before the infected program is started and then they make him incognito, hiding the hand and running in the background. It's pretty vicious, but the behavior of the virus! Currently, the virus can not see the images (. JPG,. GIF), sound files (. WAV. MP3, etc) or video files (. MPEG, etc), but it's probably a matter of time.HP 510 battery
There are also macro viruses (macro viruses), the tabernacle of macros in Office applications like Word or Excel and e-mail viruses to interfere with the mail.
Finally, the worm (worm) is a virus, through the network and spreads message and therefore no physical or logical (or hard drive or folder, etc.). Its purpose is mainly to saturate the bandwidth of the network lead to a computer HP Pavilion DV5 battery failure.
Add two distinct forms of "spyware". The Trojans (Trojan), which is actually a "Trojan horse", ie a malicious program that can each user to accidentally download hacked, usually by clicking on the links of a page (spoofing) or banner to this area and that means a hackers to remotely access your computer HP Pavilion DV3 or is it possible to extract data.
In this category are the famous botnet networks of zombie PCs that are discussed.
Finally, there's Cookie (spyware), a program that applies as citizens and "cookies" that are discussed on the sender information on the environment of your computer or the user profile installed .
The Trojans and Cookies
If the Trojans and cookies (spyware) are not viruses, they produce effects just as disruptive and undesirable for the victim.

Botnet networks: the zombies
Networks, the most vicious "botnets" are. A virus can hide another, download a different virus. Work, and some variants of the worm "Mydoom" e-mail. It welcomes you with an example of "Hello", "Remember me?" or send photos so called, but actually tried the Trojan Backdoor Surila in Visual C + +. Download
Its "payload", his office or function is to create a proxy server on your PC Toshiba Satellite 1800 battery, making it available to spammers through a secure channel protocol in IRC (Internet Relay Chat).
Installed on a network, the virus behaves like a program (a script automatically) and appears to system administrators and ordinary users. Of course, installed on a PC isolated processes displayed in clear text and can be identified.
Within days, an attacker can quietly take control of thousands of "zombie" computers in the world are distributed, forming a so-called "bottom-network" or "botnet".
Cybercrime experts from IBM Internet Security Systems (see blog Intelligence X-Force) discovered that it was possible to rent a botnet consisting of 150 000 PC Dell Laptop Battery for the modest sum of $ 350 per week! These are PC to relay spam. And for botnet cyber criminals with impunity and lead a campaign of spam (flood), without the knowledge of all rent. Your goal is to "launch" of the mail servers of large companies in the amount of traffic.
Symantec counted 6 million zombie computers SONY VAIO VGN-FW139E/H battery worldwide during the second half of 2006 increased 29% over the previous six months. However, the number of servers used to relay commands to the fall of zombies (the "bots") to 25%, indicating that the botnet owners have their networks and increase the size of existing networks.
As this article from Panda Software, said the Apple iPhone was only sold (July 2007), it was already the subject of an attack by one of 7,500 zombie computers in the botnet Trojan "Aifone. was "aimed at phishing (spoofing a) page of the iPhone. com. You can find more details in the article on the iPhone.
Everyone knows the Internet is the hunting ground of pirates (hackers), and the prey of evil viruses, spyware (spyware) and spam others. Faced with serious consequences that their actions can be triggered for a company, all these Dell Inspiron 1525 battery forms of activities as crimes and punishment as such. We'll be back.
All Internet users who have been or may one day become a victim of the acts of these criminals, we will focus in this article on the operation and methods of protection against viruses, phishing, spam, spyware and other "social engineering". To avoid this article, we will detail the risks and threats to our IT infrastructure, system vulnerabilities and software and how it protects HP Pavilion ZD7000 battery itself in the article on the prevention of hacker attacks.
Virus
All the risks that threaten the security of our computer, the virus is the most common. What is a computer virus? This is an unwanted program that installs on your computer without your knowledge. Lines of instructions telling him how to act, to multiply and infect other programs and other computers.HP Pavilion DV2000 battery
As stated by Microsoft, a computer virus is a program of a few kilobytes. Worms like Slammer (aka Sapphire) are only 400 bytes.
Windows, a fertile environment for viruses
Note that once the prerogative of the environment of Windows virus has always been the main target of virus writers. In fact, you almost never have a virus or spyware related in environments such as Unix and Mac OS X or Linux. Why?
These are the operating system manages computer HP Pavilion DV9000 virus, do not take the hardware platform, Intel or PPC Mac, for example. So the fact, do not install an Intel CPU in a Mac to make it more susceptible to viruses and other malicious actions.
The security model of Unix Mac OS X will be assumed by default designed to protect the system against threats to platforms other rule. We can say that Mac OS X since the beginning,SONY VAIO VGN-AR830E battery was designed with safety in mind, knowing that the "zero risk" does not exist.
And in fact, there are some viruses that attack Mac, as "proof of concept" test virus as "OSX.Macarena" but they are not really there to destroy (their virulence your installation directory is limited, and they easily melted), but Dell Inspiron 5100 battery designers who can demonstrate environmental pollution.
It is, as Kaspersky, said in a report, not on Mac OS X is immune against the virus, only better protected against attacks. As proof, the end of 2007, the first Trojan (OSX.RSPlug.A) Apple has addressed and explained in this article. Now he can qualify for the security of Mac OS X. Stay tuned.
However, it is not the idea of installing a Windows partition on your Apple for example (via BootCamp), it would again open up your system for SONY VAIO VGN-FW350DH battery viruses and spyware.
Note that your system is just as vulnerable, if you have a virtualization software such as "Parallels Desktop" or another solution "Virtual PC for Mac" to use to create a Windows virtual machine on Mac OS X. However, Mac OS X partition will be protected forever.
Note that this attack very few viruses that can run multiple operating systems despite the differences inherent in any software architecture. This is the case of the virus "Bi.a" written in assembly language, which operate both Windows and Linux. But even here there is only a "proof of concept" not really malicious viruses. However, after Kaspersky and SANS, in the future more and more viruses of this strain to become virulent. This has already been infected with virus beam, Windows PCs and PDAs launched in February 2006. In short, no Toshiba PA3285U-3BRS battery platform is invulnerable, but some more than others ...
This vulnerability in the Windows environment and the price for some innate wide licenses, why in the space of a generation (1981-2007), he had a monopoly, Microsoft has seen its market share, reduced to less than 40 % in favor of Unix, Linux and other Mac OS X. At each of the lesson.
This clarification takes place, to describe in detail the functionality of any computer Toshiba PA3465U-1BRS battery viruses and how to eliminate them.
Evolution
Dozens of new viruses are spread daily on the Internet, especially from the new republics of Eastern Europe, whose population is likely to be unemployed, but skilled Toshiba Satellite A10 battery and Western Europe (France, Southern England, Flanders, the Netherlands), the United States and the Far East.
In 1990, he was given 200-500 viruses under DOS with an average increase of 0.6 virus / day. Since then, the number of viruses has doubled every year with an acceleration of 1992. In the year 1996 exceeds the threshold of 10 000 virus. In 2000, there were 50,000 viruses.
List of viruses Kaspersky Today, almost 550,000 and 213,193 signatures. The software "NanoScan" Panda is able to identify more than one million signatures!
You can now ask whether the two anti-virus is as complete as the other, knowing that one has twice as many signatures as his opponent? The answer is "yes, probably" because it must be a comparison to be sure. We'll be back.
In fact, some Toshiba PA3107U-1BRS battery companies create a single signature virus, but it identifies many forms of viruses. So arbeitet and Kaspersky. In fact, transfer some worms (worms) and come in more than 400 varieties, as are many additional signatures! These polymorphic as "whales", a virus just 10 KB in 33 existing variants. In addition, a competitor for reasons of strategic business practices or as to create as many signatures as viruses and mutants, the total of an impressive number of signatures that can actually be two to five times higher than will be giving its competitors.
Also note that the virus is like nothing Kaspersky Virus List of encyclopedias encyclopedic list and make a small fraction of all existing viruses. Your best source of information are also Toshiba PA3399U-1BRS battery forums. We'll be back.
The elimination of viruses and other malware is an ongoing battle, as long as there are computer criminals will take. It is not for nothing that McAffee has chosen this name have you ever noticed that it means "make a fresh" subscribe, in other words, you buy our anti-virus software. In fact, the daily update ...
In November 1991, David M. Chess High Integrity HP Pavilion DV5000 battery Computing Laboratory IBM reported in the "Virus Bulletin" newspaper, about 30 viruses that were responsible for attacks around the world. Today they are the work of about 180 viruses, as explained WildList Observatory, which monitors the activity of the virus via the Internet.
Types of viruses
Are grouped into five major viral families. Boot virus in the boot sector of a hard disk that is read when the computer HP Pavilion ZT3000 starts to hide. These viruses replace the boot sector with a copy of itself and again the region of origin to another part of the disk. It goes without saying that even after formatting the hard drive, they are still there!
Then came the large family of viruses, the application executable (. Exe,. Com,. Sys. Inf. Dll. Vbs, etc) to infect. They replace the startup file before the infected program is started and then they make him incognito, hiding the hand and running in the background. It's pretty vicious, but the behavior of the virus! Currently, the virus can not see the images (. JPG,. GIF), sound files (. WAV. MP3, etc) or video files (. MPEG, etc), but it's probably a matter of time.HP 510 battery
There are also macro viruses (macro viruses), the tabernacle of macros in Office applications like Word or Excel and e-mail viruses to interfere with the mail.
Finally, the worm (worm) is a virus, through the network and spreads message and therefore no physical or logical (or hard drive or folder, etc.). Its purpose is mainly to saturate the bandwidth of the network lead to a computer HP Pavilion DV5 battery failure.
Add two distinct forms of "spyware". The Trojans (Trojan), which is actually a "Trojan horse", ie a malicious program that can each user to accidentally download hacked, usually by clicking on the links of a page (spoofing) or banner to this area and that means a hackers to remotely access your computer HP Pavilion DV3 or is it possible to extract data.
In this category are the famous botnet networks of zombie PCs that are discussed.
Finally, there's Cookie (spyware), a program that applies as citizens and "cookies" that are discussed on the sender information on the environment of your computer or the user profile installed .
The Trojans and Cookies
If the Trojans and cookies (spyware) are not viruses, they produce effects just as disruptive and undesirable for the victim.
Among the cookies include "VirusProtect Pro", a fake anti-spyware is exactly what is installed with the Trojans' Zlob.Trojan "and its variants. Do not rely on the site (which I do not tell you the URL ) without having first installed an anti-spyware or anti-virus on your PC HP Mini 1000 battery when the contamination is guaranteed!
