I seem to have a virus on my 233MHz PII Win2K Pro system.
pc-cillian causes the virus to hog all cpu time so that anti-virus software will not run. The process viewer under task manager is a gray screen. Hijackthis is terminated as soon as it starts. Process Explorer will not start. Internet explorer will shutdown if I try to go to an virus related website. Regedit will not run. The virus retains these abilities if I go to safe mode. Ad-aware does not find anything. As long as I don't try to remove the virus, it lets the system run as normal only slower. If you try to remove it, the system grinds to a halt due to cpu usage going way up. Task manager will let you kill a user program and monitor cpu usage. Only the process termination screen is affected. I am having to use my laptop to type this message.
I downloaded the gaobot virus removal tool from norton and changed the file name and executed it from a floppy. It did not find the virus on the system.
Basically, I can't identify the virus so as to try to remove it from my System.
