Some time ago my Antivirus ONE stopped scanning with the annoying 'Antivirus Quit unexpectedly".

It will scan Adware but not the files.

I have completely remove the app, files and all, and restarted my iMac.

I have recently bought a new iMac but it will not work on this one either??

I have Cleaner ONE pro & Unzip ONE and they work fine.

If anyone can help I would be most appreciated.
