We check files before they're approved, it's rare if we accept a file that actually has a virus. If you have avast I highly suggest you uninstall it since it's garbage anyway and try AVG or something.
do you have the free version of it and you might vomit but i have norton ' - - - Updated - - - every time i try to open a hack it doesnt work
Do you have some kind of ZIP program installed that you can use to open the hacks? Also, like the others say, probably get a better AV.
