I have identical firewall problem/error code as 'IAlwaysBSOD'. (Windows 7 x64 Svc Pk 1). Followed exact instructions posted by ripbox, did not seem to change anything, still same problem. All firewall dependency services (Base filtering engine, Rpc) are on auto and working fine. Checked out Windows Firewall Authorization Driver in device mngr, also ok. I've upgraded to latest Java version for my OS. I had earlier problem with Windows Update, but finally fixed that with MSfixIt download, so now I have most recent updates. I am also running M. Security Essentials, am considering uninstalling and re-installing that. Does anybody have ANY ideas about how I could fix this? Thanks for your help in advance.
