Guys,
this is the VAC Anti-Cheat sticky on the Steam forum:
http://forums.steampowered.com/forum....php?t=1385172
If you read the paragraph and check the links under "How do I know if a server is VAC protected?" you will see that a VAC shield should be shown alongside the servers in the Steam Server listing (open Steam and go to Steam.... Servers on the commands at the top of the Steam panel.
I have been unable to find ANY CoD servers on the list of 2,359 servers it eventually came up with so I don't know if the VAC shield even applies. I have never seen that particular Steam server loading screen so I suppose you only get that if you connect through the Steam server list instead of the game.
Can the Server guys tell us if they have set up VAC protection or is that what 'Security' means?
