Firewall blocks everything after TrojanZeroAccess ExtBlockAll2
Recently had a malware infection - Since that time ZoneAlarm no longer works. All traffic is blocked unless Internet Zone Security is set to Med. No Prompts for Program control occur, Log shows ExtBlockAll2 Personal Policy, and quite a bit of traffic (Type Firewall) with no "Program" alert types listed. If you start clicking 'add to trusted sites' to the Firewall prompts, more stuff starts working, but it's almost as if This has replaced the program control. Uninstall, Clean.exe, and re-install do not resolve this.

Then the malware has damaged core system files. I am not surprised as the changes by that rootkit based infection are very difficult to revert. I would warmly recommend to fully format the hard disk, reinstall the OS clean and ensure you are fully up to date before installing ZA.
