There are 3 kinds of bans you can get in CS:GO
- VAC Ban
If VAC found something on your Computer that is a cheat/hack whatever you get VAC banned.
- Untrusted
The serverside anti-cheat found something, goes into VAC Ban some time.
Has nothing to do with your file, if it was crypted or whatever.
- Overwatch Ban
Has nothing to do with the 2 above.
If you get ~10 reports in ~24hours, your game demo will get sent to overwatchers, which decide if you get an OW Ban.
Summary: Your untrusted had nothing to do with VMP, Enigma, Hashchanger or whatever you used to play safer, it seems like the server detected that you manipulate the game or whatever.
