In a system in my locality, there is this stubborn Win32 Services virus that is refusing to get killed. Though the system already had Norton 2005, it affected the system. When I tried to install some other programs on this machine, the SFX applications failed to get installed and reported CRC difference, that is as son as the program unpacked some files in the temp folder, they got modifies and as a result, I could not install many programs including Antivir that I had with me. I tried to boot with the Live Linux Bit defender, it too could not disinfect or remove this virus. Is there any other tool available for this??
