    A couple of days ago I contracted a virus. Initially I assumed that my virus scanner (Avira AntiVir) had caught it, but the next day a fake virus infection warning and glut of popups to an obviously fake virus scan website indicated otherwise.

    It immediately attacked Spybot (to the point where I couldn't even install a new version), but didn't seem to consider my virus scanner a threat. Through multiple scans I've managed to get Spybot working again, and the popups and the fake virus alert have long since stopped, but there are still bits and pieces hiding around somewhere trying to cause problems. Earlier today, for example, it tried repeatedly to alter my registry by adding something called awepajor.dll (might've been awepajon), but that seemed to stop after a good ten minutes of denials.

    Avira AntiVir recognises the virus as a trojan called FakeVir.LSK. At the moment there are two files Avira is consistently associating with it, all in the system32 folder; 303357.exe and frmwrk32.exe. I've quarantined both of them but I'm also getting several registry changes/additions that are reappearing after every restart.

    I've also got the latest version of HijackThis downloaded, in case you want a log.

    Can any of you help me, please? :)

    I'm not a fan of bumping my own threads, but this virus - at least I believe it is caused by the virus - has been erratically attacking my system for the last couple of days. The most serious incident was the spawning of several Vundo.gen viruses that, while I did quarantine as soon as possible, crippled my PC's processing speed and created a whole slew of annoying little trojans and spyware that I'm still not certain I've fully removed.

    It's starting to seem like this virus is changing its tactics on a regular basis and I'm not entirely certain I can deal with them all on my own. Every time I think I've finally gotten rid of the worst of it something new and unpleasant pops up. It's more than a little frustrating.

    I'll include a HijackThis log for the sake of being thorough.

    I may not be an expert at it, but something caught my eye: 020 - Winlogon Notify: pmnkJApn - pmnkJApn.dll (file missing). When I initially spotted the Vundo virus Spybot was giving me several warnings about something attempting to add pmnkJApn in Winlogon Notifiers and (AC6AF0BC-B2C3-452D-B82D-6F162597F405) being added in Browser Helper Object. I assumed they were the virus trying to hijack my system and repeatedly denied them.

    I really hope that wasn't a stupid thing to do.

    Edit: After running both scans (Avira/Spybot) I've come up with only four hits, all on Spybot: one BurstMedia and two MediaPlex tracking cookies and a notification that Microsoft Windows Security Center has been disabled. All three have been "fixed" before and continue to return on startup.

    Not really sure what it all means, but it's kind of nice to no longer be picking up traces of FakeVir and Vundo... I think.

    Does this mean my PC is (mostly) clear of the virus, or have I missed something that could bring it all back? Any suggestions on what to do next?

    No real progress yet. FakeVir is gone and hasn't come back but Vundo, Virtumonde and the disabled security notification keep coming back regardless of how many times I quarantine or delete them. I've even tried the Vundofix program, which a friend had better luck with, but apparently whatever I've got is an undetected variant.

    It's still trying to mess with Winlogon (which is currently consuming far, far more CPU than it normally does), although the virus seems to stop trying to alter it when I disable the internet connection. I'm not quite sure what that means.

    Still, help would be extremely appreciated. It's obvious I can't get rid of this thing on my own.
