How to remove computer vireses from infected system

In almost all the cases, a computer virus can’t run without operating system running as well. As long as you don’t start your operating system, the virus remains essentially inactive, and has no way to hide, fight back, or transmit information. The goal here is to freeze the virus so you can find it, delete it, and move on with your life.

There are a number of tools that will give you this power over the virus. Kaspersky Rescue Disk 10 is one of them which smartly removes viruses form the infected machine. Kaspersky Rescue Disk 10 is designed to scan and disinfect x86 and x64-compatible computers that have been infected. The application should be used when the infection is so severe that it is impossible to disinfect the computer using anti-virus applications or malware removal utilities (such as Kaspersky Virus Removal Tool) running under the operating system.

In this case, disinfection is more efficient because malware programs do not gain control when the operating system is being loaded. In the emergency repair mode, you can only start objects scan tasks, update databases roll back updates and view statistics. You can download by clicking here for free.

Once you have your CD/DVD or USB drive, setup your machine's BIOS to boot from CD/DVD or USB accordingly. CD/DVD or USB drive you created has a fully functional operating system built into it. When your computer starts to run it, everything gets loaded into the RAM and follow the instructions.

General requirements:

• 480 MB available disk space
• CD-ROM/DVD ROM
• Internet connection
• Computer mouse
• Internet Explorer 8.0 and higher
• Windows Installer 3.0 and higher

Computer Virus

What is Computer Virus? A computer virus is a human written computer program or a piece of code that can replicate itself and travel from one computer to another infecting them. The term "virus" is also commonly, but erroneously, used to refer to other types of malware, including adware and spyware programs that do not have ability to replicate itself. Malware includes computer viruses, computer worms, ransomware, trojan horses, keyloggers, most rootkits, spyware, dishonest adware, malicious BHOs and other malicious software.

The majority of active malware threats are usually trojans or worms rather than viruses. Malware such as trojan horses and worms is sometimes confused with viruses, which are technically different: a worm can exploit security vulnerabilities to spread itself automatically to other computers through networks, while a trojan horse is a program that appears harmless at first but hides malicious functions. Worms and trojan horses, like viruses, may harm a computer system's data or performance. Some viruses and other malware have symptoms noticeable to the computer user, but many are surreptitious or simply do nothing to call attention to themselves. Some viruses do nothing beyond reproducing themselves.

Some types of computer viruses

• Viruses: A virus is a small piece of software that can attach itself to a program such as a spreadsheet program. Each time the spreadsheet program runs, the virus runs, too, and it has the chance to reproduce by attaching to other programs.
• E-mail viruses: An e-mail virus travels as an attachment to e-mail messages, and usually replicates itself by automatically mailing itself to dozens of other people in the victim's e-mail address book.
• Trojan horses: A Trojan horse is also simply a computer program. The program claims to do one thing (it may claim to be a game) but instead does damage when you run it (it may erase your hard disk). Trojan horses have no way to replicate automatically.
• Worms: A worm is a small piece of software that uses computer networks and security holes to replicate itself. A copy of the worm scans the network for another machine that has a specific security hole. It copies itself to the new machine using the security hole, and then starts replicating from there, as well.
