Moved from Data Backup to VirusScan.
If you restored the files then they would reappear where they were before until VirusScan scans the next time and it all starts over again.
If you clicked remove, rather than restore, then they are gone forever and can't be retrieved.
I suspect you did the latter if they haven't reappeared.
Check that they aren't quarantined again.
Double-click the taskbar icon to open Security Center
Click Advanced Menu (bottom left)
Click restore (left)
Click Files (top left)
If they are there again you are going to have to disable VirusScan temporarily and report them to the Threat Center in the hope that they can disable their detection in an update.
See this thread regarding that:
