How do I get rid of malicious spyware, malware, viruses or rootkits from my PC?

I caught the Trojan right away, I think, but both my McAfee & Win 7 (x64) firewalls are not able to be engaged/turned on now. MS Error Code 0x80070424 when attempting to turn on Win 7 firewall. No viruses. Swept it with McAfee AV, Malwarebytes Anti-Malware, Microsoft malware removal tools. Followed Microsoft's three courses of alternative actions they posted for instructions for getting the Win 7 firewall back up and on. Nothing. Same error code. The post just said see MS support if those fixes failed.

So I removed McAfee altogether. Still Win 7 (professional version) firewall won't come on; and clean of detectable bugs.

And I'm fully updated with MS Windows 7 updates as well, which is no longer automatic, that too a legacy of the trojan bug I think. Any thoughts on how to get the Win 7 firewall operational??? And auto updating reengaged?

    honestly, unless there's some compelling reason not to, wiping the system is the best solution – Journeyman Geek Jan 11 '12 at 00:44
  • Agreed. The chances are some system level files are broken or missing. W7 doesn't have a repair-install so starting over is the best bet. Nuking it from orbit is the only way to be sure. – Paul Jan 11 '12 at 03:19

I would give TDSSKILLER a go. You may still have a rootkit.
