Computer blocking VAC?

Okay so I'm using an aimbot and ESP on a flashdrive then I load it up, take the flash out and play on MM but then I get kicked 1/2 way through saying my computer is blocking VAC servers and I have to restart my computer (So I get banned - can't get in within 3 mins) but is there anyway I can stop the kick? (I am not VAC banned)

It is probably cause by the cheat. Could you post what cheat it is? If it is a paid one, private message me as it's against the rules to share them and so on.

No it was T_T Phoenix Black - it's never been detected for me but it does this instead now
