So I bought the game on steam a while back and finally installed it. Once I went to play it (after it installed physx and such), my antivirus popped up and complained about game.exe being malicious, doing code injection, and so on, and wanted to quarantine the files (which I let it, for now).

Is this a known issue, what's going on here?

Thanks.

Just a false positive from your anti-virus.

You can always try to upload the file here http://www.virustotal.com/ to have to check by more than 20 different anti virus, so to make sure. But I can assure you there is no malware or virus in the game and code.

Thanks.
