Balon, I tried your registry fix, but when running the second registry file (firewall.reg) it gives me this error:
"Cannot import D:\Downloads\firewall.reg: Not all data was successfully written to the registry. Some keys are open by the system or other processes." I'm afraid a virus may be accessing the registry entries this file is trying to change, but I did a quick scan with the Microsoft Safety Scanner and it only found one infected file and deleted it. I also have Avast! real-time virus protection shields running.
