McAfee is a piece of shit, for one thing. Does it show the exact location of the virus?
You should install this and post the log file in this thread:
http://filehippo.com/download_hijackthis/You can manually shut down the virus using HijackThis if you know what to look for. If you have the name of the file, that would be a good start.
You might also want to try scanning the file or the folder the file is in with this:
http://filehippo.com/download_avast_antivirus/ That is, if you know the location of the file, which be a good thing to have. You could try scanning with McAfee in Safe Mode or you can do a Boot-Time Scan with avast! Antivirus. If you have the name of the virus, that would be helpful. You can Google the name of the malware and see if other people have figured out solutions to fixing that little bitch of a virus. You might also be able to shut it down at startup via msconfig, unless the virus is attached to a program that, when opened, the malware is activated...that\'s always a pain in the ass. Start > Run > then type
msconfig
