I'm using Vista Ultimate 64-Bit and I initially ran through a complete performance check: Anti Virus, Backup, Defrag, everything... Not more than 6 hours later, the security status went from green to yellow indicating "I have important new files that changed or were not backed up". What caused this to happen so quick and how often does this assume you will be backing up your computer? (I don't think I even used the computer for that 6 hour period from when it moved from Green to Yellow.
Thanks.
