As the "computer guy" in the neighborhood, I've been asked by a friend to help disinfect his 2004 Dell Inspiron 5100 (about six years old) which runs Windows XP. I don't have all the details I'd have if the machine was mine, but there are a few items that might be worth noting:

1 - He definitely has the Total PC Defender thing running, and it does its best to prevent Internet Explorer from launching, so downloading software to the machine is a problem. I've been using a flash drive to transfer files to it from another machine (although none of the anti-malware stuff I've run - malwarebytes, superANTIspyware, Spybot - S&D - has touched it). I'm positive that there's more malware on the system, but that's the most obvious right now.

2 - He had a very old, no-longer-supported version of McAfee installed, but I'm not even sure if it was still getting updated definitions. I tried to replace it with something more modern, but it wouldn't un-install. I hacked at it to prevent it from running, and that seems to be when the Total PC Defender reared its head. It had to have been on the machine prior because there was no online activity after stopping it.

3 - Tried running some things in Safe Mode with Networking, but for some reason couldn't connect wirelessly to do any downloads.

4 - I disabled nearly everything in Startup (not sure how I was lucky enough to run msconfig because it wouldn't load previously) and that seems to have helped give me more access to the machine, but obviously the malicious software is still there.

5 - I do have a ComboFix log which I can upload at any time.

Thanks for any help you can provide!

Yes the type of Trojan you have is really annoying and it probably won't even let you get Malwarebytes' Anti-Malware
You don't have to do this these stuff.
  • Make sure you can go to Microsoft website
  • Try in Safe Mode With Networking
  • If you can't you have to wait until one of those Bleeping Computer guys give you some stuff
  • If you can then download Process Explorer
  • Save it to desktop
  • Make sure you in normal mode
  • Now look for suspicious processes in Process Explorer
  • Right-click processes then click suspend
  • Now you can just wait for a Bleeping Computer guy to provide you with programs.

This is my first time using Bleeping Computer. Could anyone tell me how long I should expect to wait before receiving help?
