Hey all... new to the forum. Was hoping I would be able to solve my wife's laptop issues on my own, but I guess I was wrong. It's a few year old Sony VGN-N160G. A few days ago, she went to Myspace and the Antivirus Soft popup got her and that's where the problems began...

I ran MalwareBytes and cleared the 2 issues it found. Restarted and the Antivirus Soft was still there. I found another site that had a different way to fix it, and I ended up just deleting the exe file out of the Application Data directory that it was in. Restarted and everything seemed fine. I ran another MalwareBytes and it came back clean. I ran AdAware, but it froze halfway through. I thought nothing of it and assumed all was well.

The next day, the wife went back to using her computer as normal. After not long, she had already had to hard shut down a few times after it had frozen so she stopped using it. This weekend, I started working on it some more. Started by doing a system restore to a day or two before Antivirus Soft popped up. Then various scans would freeze after the computer was on for about an hour. So I rebooted in Safe Mode and ran a few scans. I don't think MalwareBytes found anything, and Adaware found nothing and AVG found nothing. Rebooted to normal mode and after a little while it would "freeze" and require a hard shut down. What was weird was that when the computer "froze", anything that was open worked fine. Meaning that I could click through tabs on MalwareBytes or even cancel the scan that had stopped scanning and it would pop up an "are you sure you want to cancel the scan" window. It would act completely normal except that the scanned files weren't changing so it had obviously frozen. I checked the Task Manager and all processes (even system idle process) were at 0%.

Did some more testing around and determined that if I left the Wifi switch to the off position, the computer wouldn't freeze at all no matter how long I ran scans or anything. But if I switched the wifi back on and it connected, within minutes (or even seconds one time), it would freeze and all processes would go to 0% CPU.

Downloaded Spybot: S&D, rebooted to safe mode and scanned. It found 2 Virtumunde trojans and cleared them. I did some research on these and found that they can be a pain, so I downloaded from here VundoFix and VirtumondoBegone; ran them and had no problems. Also ran CCleaner somewhere in there as well.

My brother suggested ComboFix, so I got that, ran it, and it froze in the "rebooting windows..." phase. I'm guessing that was because I had to turn on the Wifi for the recovery console, that caused it to glitch. Hard shut down even though it said to let ComboFix do the reboot. Restarted and ComboFix finished up. Spybot S&D popped up a bunch of registry entry changes though; I'm assuming things that ComboFix did?

While I was waiting, I decided to start a topic on here and saw where it said to NOT run ComboFix unless instructed to do so. Sorry about that. I have the log file, but I'll wait until you instruct me as to what to do next. Any help would be greatly appreciated because, as you can see, I've tried a lot of different things and am coming up short in terms of positive results. Many thanks in advance, and hopefully I haven't actually screwed it up worse than it was!

you may lock this thread. I tried running the diagnostic, but the computer kept freezing. So I decided it was time to make some recovery discs, format, and start from scratch. As of 4AM, her computer is good to go. Thanks for your quick reply. I will keep this website in mind when we have our next computer issue.
