    Oh okay. I had started Vundofix before you had replied though, so I figured I'd just finish it. I'll cancel it and do what you said then.

    Fair enough.

    Okay. Malwarebytes keeps freezing and I renamed the .exe. Either I didn't do it right (I think I did) or something else is going on.

    Try GMER. We may have some rootkit issue here.

    GMER was inconclusive. I did however get Malwarebytes and SUPERAntiSpyware to work. They both picked up a bunch of trojans. I'm assuming I should change any important passwords on my computer? Super was able to remove the fake software on reboot, but Malwarebytes couldn't run on reboot for some reason. Here are the logs.

    System restore IS a viable option. Previously, before I ran the scans and removed whatever I couldn't boot into safe mode, but now I can. I have plenty of system restore point from before this occurred, so if you recommend I just do that, I can.

    Don't. Never use system restore on infected computer, because you're gonna bring back most of garbage, which was already cleaned.

    I'd like to see GMER log, and fresh HJT log.

    Yeah. That was my main concern.

    I don't have the Gmer log since I forgot to save it (I ran the scan overnight and it finished around 6 AM, so I wasn't on top of my game then), but I'll run it again and then get you that HJT log.

    Thank you. GMER doesn't take THAT long to run.

    Save 20% on AVG Internet Security 2012 Suite!
    It had been running for at least... an hour before I went to bed last night. It took 4 hours to finish the Malware scan, which is what? Quadruple the normal time?
