When I update IS 2008 the engine version and the virus definitions are updated, but everything else will not be updated. Modules like: vsserv.exe, uiscan.exe, scan.dll and al others remain the same. I have downloaded the last version of Bitdefender IS 2008 before that my version of bitdefender was 11.0.13. After all updates the build number stays the same. On the bitdefender forum I have seen that some modules versions are updated but not for me. I have tried everything from uninstalling BD with the uninstall tool, cleaning the registry with ccleaner and jv16. Tried a clean install of Vista Ultimate even cleaned some inf files created by BD. On my second computer everything was the same (XP SP2, full update, second try with clean install of XP SP2 without update),still same results. At this moment bitdefender has run autoupdate and again no difference. Sorry for my bad english!
