Banned :(

When I play online, there cheat is detected.
Although I do not have to cheat in this time.
Can you help me??

Thanks

(Sorry for my bad english)

It means you are permanently banned sorry nothing you can do about it. VAC picked the cheat up previously and it takes a while for steam to ban players so yeah... Which hack did you use last? The only way around this is to create a new steam account and buy another cd key.
