I got a new installation link for Total Security 2013 when I requested an upgrade. However, I cant successfully install it. The problem being that at the "Scanning" stage, the progress bar stalls and I got an error message that 5 infected files were found on my PC and only 3 could be deleted and that a reboot was required. When I made a reboot, Windows shows a blue crash screen and reported there were incorrectly-installed files on my PC and that it was damaged. I made a successful system repair and attempted to re-install the Bitdefender solution but the cycle repeats just as it was, that led to the crash. I have Windows 7 64-bit. Thanks
