I recently bought a key off G2A.com, and I have previously bought a Lego Star Wars: Complete Saga key from them before with no issues, and it opened perfectly fine on Steam. I downloaded Republic Commando with no issues, so when I open the game to download it, Steam would not open it and McAfee gave me a warning saying that it quarantined a file in the game, saying that it's a virus. I spoke with the seller of the key, who is very popular and has a 95% positive feedback, and with support, saying that the game should contain no viruses since the key issued was new and had no virus. Attached is a file of the said virus and Steam not being able to open. Please help me out asap. Thanks!
