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?
