Hi,
today I upgraded to TS 2010 after uninstalling using the BD uninstaller. Quick scan after installation was ok. Then I started a deep scan. After about 20 minutes Bitdefender Report Wizard popped up: "BD Security Service has encountered a critical error!"
I sent the scan log and crash dump to sendspace.com:

I'm running XP Home SP3, no other malware tools.
