Free Virus and Trojans Removal Tools

There are many methods of protecting a computer or network. One of the methods is by preventing viruses, trojans and other types of malware to infect a system or network.

It also adds a registry key in the Run section under HKEY_LOCAL_MACHINE. The following free antivirus software will succeed or fail to remove the infection:
