My son is a gamer, and it appears that Comodo is either blocking or containing some of his legit games as viruses. Is there a way to exclude the folder his games are in from being scanned?

@Fred ,

You can try this exclusion:

C:\Program Files\ Sample Game Folder* - the wildcard ( * ) Will match all files in the current directory and sub-directories.

Other information about creating exclusions, you can view it here and also here.
