I am having this same problem after removing the FBI virus. I downloaded and ran the Windows Repair Tool as instructed. However when I check the staus of the firewall it says it is not using the recommended settings. When I click on the "Use the receommended settings" I get the error that says:
Windows Firewall can't change some of your settings. Error code 0x8007042c
