hm maybe i'm not well versed in how tf2 works but i kinda doubt that your entire pc can be hacked/have malware installed on it just by playing in a server lol

is there any real reliable source (heh) or any first hand accounts that this is the case? cause i'd believe if there were VAC bans happening and stuff but saying that simply launching tf2 can nuke your pc seems a lil farfetched
