can someone please help me. i bought the game legit from steam i did not torrent this. i updated the game when i woke up and i could not play the game because my f-secure blocked it because it had a virus attached to it now. i played the game before i went to bed and did not have this problem nor the past couple of days i have been playing. so i removed the malware through my f-secure thinking this would fix it but when i tried to play it again my steam said i was missing. the only other people with this problem are doing the dumb thing by just turning f-secure off which is the worst thing i could do. please help me

I'm not familiar with f-secure but i would report the problem to them to see if they can add the offending file to their "safe" list. Or i would manually add an exception on your end. 

 

Unfortunately there's nothing I can do about this issue on my end.
