We have 5 or 6 computers on our network that our mcafee av is catching a virus called Generic Backdoor.t, but the file that it's catching won't let us delete it. It only seems to be one file, but it's a different named file on each affected computer. You tell Mcafee to clean it and it says it can't. You tell it to delete it and it says it can't. But then you search for the file and sometimes it's there and sometimes it's not. If you scan the computer for viruses, it finds nothing. I scanned with http://housecall.antivirus.com
and with F-secure, and with our Mcafee. None of them found viruses. Yet, you logoff and log back into windows and Mcafee will again display the little hand squishing the bug and say it found the virus again in the same file.
How do I get rid of this? How can you stop something that doesn't get found when scanning the system with your AV?
