I play Counter Strike: Source and Half Life 2: Deathmatch before and I now have the games on my Mac via Steam; when I used to play on Windows I would often download custom maps in-game (I would join a server and it would automatically download the map) and I am a bit concerned of this because I am now wondering, is that a safe thing to do? Since I have a Mac I am worried that I might get a virus or something from these 'foreign' maps I am downloading (I downloaded one but deleted it after). Is it possible to get viruses, spyware, malware, etc. from downloading in-game maps on games from Steam?
I'm hoping you would say "No, you can't get viruses from downloading maps in-game. Don't worry about it" or something like that LoL.
P.S. In case you were wondering what map I downloaded it was bm_flatgrass or gm_flatgrass I think.
