Steam Support will not disclose the cheats that were detected running on your system or the date and time the infraction took place. Any requests for this information will be ignored. VAC may not ban you immediately - the cheating violation may have occurred days or even weeks before the ban is apparent on your account. So they would not help,so I wiped my pc and reloaded windows 7. I went to Walmart and purchased black ops for pc and installed it on my new computer. One week after playing it they banned me again for BLACK OPS!!! Here is what they had to say.

Hello,

A staff member has replied to your question:

Hello , I understand your frustration in this matter; however, our system has confirmed that the ban was applied legitimately. A VAC ban applies to the game(s) regardless of who was using the account at the time. It does not matter if you let someone use the account, or if the account was being used without your knowledge. It is your responsibility to safeguard your account against such activities. I am sorry, the VAC ban on the game(s) will not be removed. Before continuing to use Steam and Steam games on your computer, please remove all cheats from your system. Failure to do so may result in further VAC bans on the account. Please refer to the Steam Subscriber Agreement and the Rules of Steam Online Conduct if you wish to review our policy regarding this matter. Steam Subscriber Agreement. I will never buy another game from Steam, and I suggest that you do not buy any games from them also. $120.00 down the drain for what?
