Zone Map Domains flagged as malware ?

Something unusual. Webroot CE 9.0.32.58

I was shifting files around the other day and making image files for backups, when webroot suddenly lit up identifyiin multiole files which we had previously scanned with no problems and of specific interest all my internet zone domains were red flagged.

Had to disable Webroot for the duration.

I do use Spyware Blaster to add site restrictions?

What was that?
