Hello. My brother and I share the same PC. He tends to download (I'm not sure how to put this...) "junk" and I don't. In any case, I have the following security set up: 1. Kaspersky Internet Security 2013, 2. DefenseWall, 3. HitMan Pro, and 4. Malwarebytes (on demand) I've seen him click away at "OK" when DefenseWall asks whether or not to allow access and sure enough our pc is infected. Would it be an idea to replace DefenseWall with SandBoxie such that no choice is given to him at all? Thank you again.
