You are right. Crossfile is a computer game.
Yes. it's also a method by which ATI graphics cards can be used in multiples. Though without more information anything will just be a guess.
-what happens when the AV is not disabled?
-is the AV updated?
-has this always happened? If not, what changed?
ATI Crossfire will often trip a false positive with some AV software when enabled. Truly though I don't see how a debate over where the post should be is very helpful, one way or another; it can always be moved.
