I have recently been thinking about buying Garry's Mod on Steam, however in the past Steam has given me...issues. Back on my old computer, I had steam and only had 1 game, Team Fortress 2, however I learned a similar game went free on steam as well, Gotham City Imposters, so I decided "why not?" And downloaded the game. It never finished, and I never understood why? Then my virus protection program STOPZilla detected a virus in the computer... Since then I have 2 new computers and I want to try steam again...but just in case, is there any reason behind Gotham City Imposters giving me a virus? And is there any way to prevent it?
