If your anti virus detected any game files as a potential virus - It's a FALSE POSITIVE. This is a common problem with FREE anti virus software. Report it as such with your anti virus program. You can also add the game ( or those files ) into exceptions.

To restore the wrongly deleted files, simply verify the game cache integrity through Steam.
