This morning I got an auto update for BitDefender on Windows XP Pro x64, restarted and found my entire system frozen. I couldn't even get Task Manager up
After several hard restarts, and waiting for the system to "unfreeze" for about 10 minutes or so, I booted to Windows Server 2003 Enterprise x64 where I had also installed BitDefender. Sure enough it wasn't long before the update came through and then I restarted and found exactly the same issue there.
Booting to safe mode in XP Pro x64 didn't help at all as the installer is not active in safe mode and I couldn't uninstall the firewall from there. So, I booted to XP Pro 32-Bit and from there, deleted the BitDefender program file in XP Pro x64 and the BitDefender Application Data folders for all the users and then rebooted to XP Pro x64.
The system was no longer frozen and I went to Add/Remove programs and uninstalled it. Removing it went well although there was a hickup or two when it didn't find some of the components. Never-the-less it completely removed it and on restart I've got XP Pro x64 back and working albeit with no firewall other than the Windows one, once again
I did the same with my Windows Server installation.
Somehow my conclusion has to be that running Windows 64-Bit of any flavor is not a proposition at this point in time, as the currently available firewall appliciations are inadequate and not bug free.
It's a pity really, because I had high hopes for BitDefender. I'll give it a day or so to see if a fix is released and then try installing it again
