It kept saying gta_sa as the suspected application but didn't go into detail on what file. It had a different IP address almost every time, however I've been thinking and I had been playing for about 5 or 6 hours in total, so maybe it was communications from the servers it was highlighting as potentially malicious but it was spamming all of them after I'd closed the game, if you get what I mean. Thanks for the help and I will continue to play for ages to come
