Hi all, I would like to share an experience I had with BitDefender Total Security 2011. The program was running fine for a while on my PC, which had a fresh install of Windows 7 64-bit on it. Then out of the blue IDS detected a malicious file, it then deleted the Windows file mcupdate.exe. This was a false positive. I received a windows error message every time media center tried to update. What is disturbing is that the file was not placed in quarantine nor was I given the opportunity to allow or deny this action. In my opinion a very dangerous flaw in their software. I was forced to restore to an earlier snapshot. I have reported this issue on their forum. When AV's start deleting legitimate windows files and you are unable to stop this from happening then they become dangerous.
