Yes it was taken care of, ensure you have the latest virus definition updates.
Once you have the latest update, stop the file system shield (or reboot) restart the file system shield. This resets the scanned count, so you should get an indication as to how it is behaving now. If for some reason it is still getting multiple scans, then you can add this C:\Program Files\MaxiVista Standard Server\MaxiVistaA.exe file to the file system shield, expert settings, exclusions (for Read Write and Execute (RWX).
No need to take the drastic action of going back to avast6.
I was getting in excess of 50,000 repetitive scans spread over more than 30 files. Did I go back, no I stuck with it giving as much information as I could and it was resolved.
