Removed all previous installs of virus, internet and malware protections. Ran registry cleaners and restarted Vista Home Premium pc. Installed Bitdefender Total Security 2012, registered and ran update utility. Everything seemed to be fine. Then I allowed windows update to run. Re-booted pc. It got as far as a black screen on my monitor and just locked there. Followed some steps I found on this forum. 1) Re-booted in Safe Mode with Networking. 2) Downloaded the Bitdefender uninstall utility and ran it. 3)Re-botted pc and started up OK. Downloaded the Bitdefender support tool and ran it. It ran for a while and just locked up.
After that I decided to run my Registry Mechanic and CCleaner utilities to clean up registry and tried to run the Bitdefender support utility again. Still locked up.
I have purchased a 3 pc package of Bitdefender Total Security 2012 and have it installed on my Windows 7 64-bit pc and my Windows XP SP3 laptop and everything runs great. What is up with Vista Home Premium?
