I have some rather large folders that are linked through junction points on Windows 7. I just tried Comodo Antivirus for the first time and found that it reported errors for a file both in the real location and in the linked location. This is a real time waster.
I put my major junction points on the exclusion list, but there are junction points and links throughout the system and it would be difficult to find them all or to keep the exclusion list up to date. The scanner should skip junctions and links.
Personally, I think this is more a bug than a wish, but I thought I’d start here.
