i was playing a game online, a person who had lost told me i'd been hacked. i didn't think much of it until someone mentioned a username that i hadn't used. then more info, the more it could have been done. i am on windows 7, i run kaspersky av, windows firewall. all currently updated. how can i tell? what do i do? kaspersky OL AV is down and has been. can anyone help? or direct through properly? thanks!
