My computer is running Windows Vista Home Premium on a Dell Inspiron 531 and recently a "Vista Security 2001" virus has made its way onto the computer. It has evaded all of my attempts to remove it; the god-awful McAffee found nothing in a full scan, disabling what I thought triggered it at startup through MSconfig.exe did nothing; deleting all temp data with CCleaner and everything I could find that could be related to the virus did nothing, and "efe.exe"--the virus itself--is not in AppData\Local like Windows Task Manager says it is. Internet access is blocked with a pop-up saying that both IE and Opera are infected (I may have found a way around this, but it may be too late). After all my attempts at removal in Safe Mode, I booted it up regularly, hoping I could get around the block by typing a URL into the Windows Explorer address bar, but instead of presenting me with the log-in screen, I met a black screen asking me to revalidate my Windows installation because "something changed." I tried using Dell's built-in factory restore after this, but after a long "Please Wait..." screen, the admin account was inaccessible; the only option was "Other User" and my attempts at logging in through it failed as it told me something like "The domain could not be found or does not exist." I haven't tried running the computer since then and my Google searches have turned up little in removing this. I'm stumped. I can't wirelessly send the infected computer anything nor use a USB flash drive as I don't have one. What do I do?
PS. I don't know where the Vista install disk is if it even came with one. We got this computer years ago before I knew anything about computers so a complete reinstall may be out of the question.
PPS. While I couldn't find the virus itself in AppData\Local, I did find a cache file that it made every time it popped up.
Edit: Did not see the other board down there the first time I looked through (despite the obvious red text). Please forgive me.
Edit 2: Thanks for moving this, Budapest.
