We have a technical service and we clean HARD DISKS from viruses, so we unplug the HD from the PC and we plug it on a clean PC for a safety clean.
1 new features would be very usefull:
1.-You can choose the unit c:, d:, etc... but if you plug a HD from another computer, avast does not review the REGISTRY as is, only like another file more.
So you can choose to review&fix the registry of the OS of that HD, because now, it only reviews the registry of the MASTER computer.
For safety we check all the HD's from a clean PC....but we can not fix the registry, only deletes/repair the files.
