Yesterday while playing an intense game of PvP...my game crashes and my anti-virus app (AVG) pops up a warning of a threat. I select to remove it...needs restart to complete. After restarting my computer I couldn't play Defiance. According to Steam's "check game cache validity" option...86 of my game files could not be validated. I am currently re-installing I think. :/
Is it possible I was hacked? I don't know why it would do that otherwise...
