Question:
Fixing a massive memory leak?

A rouge anti-virus made its way on my PC a few days ago and has wreaked havoc. McAfee, doing what it does best, let this "program" through. I did my best to figure out what was going on, and within a couple minutes I installed Vipre and scanned my PC. Apparently the rouge AV called "Security Master AV," let some of its friends in as well, and I was dealing with several trojans and malicious programs. Vipre picked up on most of these as well, and I thought it quarantined everything... it didn't. However, that marked the end of Security Master AV.

After the quick and deep scan using Vipre, I assumed the registry was still damaged, as various things didn't work as they should (ex. minimizing windows). I then decided to restore my PC to an earlier date before the infection. That seemed to work for a few hours. Then they spontaneously returned on one occasion of me opening IE8. I learned that the trojans/viruses may have had their links to the system broken and they were most likely lurking.

This time I downloaded Malwarebytes and scanned my PC. It pulled up a huge laundry list and quarantined the malware. Thinking there was more, I turned off restore points (the trojans deleted them the 2nd time around anyways), put my PC in safe mode, and deep scanned with Malwarebytes. I'll post my logs from these scans below.

Stuff from Vipre...
- Explorer.32.Hijacker - HKEY_USERS\S-1-5-21-343818398-1532298954-725345543-1004\Software\XML -1

- Packed.Win32.Tdss.s(v) - C:\DOCUMENTS AND SETTINGS\SHANE\APPLICATION DATA\7112cc4b.exe - C:\DOCUMENTS AND SETTINGS\SHANE\LOCAL SETTINGS\TEMP\Vwj.exe - C:\WINDOWS\SYSTEM32\ernel32.dll (clean failed)

- VirTool.Win32.Obfuscator.hg!b(v) - C:\DOCUMENTS AND SETTINGS\SHANE\LOCAL SETTINGS\TEMP\Ucfo.exe

I did a scan today with Vipre and it found... "Trojan.Win32.Generic.pak!cobra" - C:\DOCUMENTS AND SETTINGS\Shane\LOCAL SETTINGS\Temp\gkxk.exe

Many of the trojans that I've gotten since my first scan are repeat offenders, especially the Explorer32.Hijacker. What follows is one that I've seen many times... "Trojan.Win32.Generic!BT" - C:\DOCUMENTS AND SETTINGS\Shane\LOCAL SETTINGS\Temp\sucvdadx.exe

The only symptom I'm seeing now is memory leaking. I'm very sure there is malware still on my PC that niether McAfee, Vipre, or Malwarebytes is picking up. Nearly every process steadily gains memory usage over time, whether its all of the svchost.exe's running, Yahoo Messenger, iTunesHelper, it doesn't matter.

If any more details are needed, let me know please!

I know I made a bunch of mistakes on the way, but this is the first time I've had to deal with this. I'm pretty careful with my PC, as I built it myself back in 08', yet I'm learning as go along with this. Any help is most appreciated.

Go into your settings and tell Firefox not to remember any History.. You dont need it, if you want to remember something make a bookmark... Then disable or remove any extensions or plug-ins that you do not need. And make sure your firefox is up to date (Help -> About Firefox). If all that fails uninstall Firefox, delete all profiles and preferences, clean your registry then re-install. And if the clean installation still uses too much memory for your standards then your standards are too low :P (My Firefox is using 150mb of memory right now. 50-150mb is fairly normal depending on your setup)

Go to safe mode and try to find the source of the file. Usually in the AppData folder and it is an exe with a wierd name like A6783488237-357.exe (security tool rogue)
