Setting up the scanner

Hi all
I have just installed Comodo V4 and I can’t find any way of telling it to just scan the Operating System hdd, When I click scan it does the Main HDD, then starts on my games drive and scans all the games in that for the next 40 mins, then on to my storage drive and scans 3.000 photos, it takes forever,
What do I need to do to set for the main HDD alone?
Many thanks Robert.

Go to Run a scan and choose critical areas. That may not do the whole system drive. In that case make your own scan profile.
