Confusing ban

[Furious]

So I downloaded MTA on my work PC today and was ingame for about 5 hours, running around and playing. Then suddenly I got kicked and banned for the reason: AC #4 668P SQLbans. What is this, what software on my PC could lead to this and how to get it removed from my punishlog?

You cannot appeal automated MTA bans (you were detected as cheating), they shouldn't last very long anyway.

We do not handle / lift bans issued by the anti-cheat. The ban must have expired by now anyway.

It's an automatic MTA ban, you were detected as cheating according to MTA anti-cheat, I guess.
Must be a software you're running on your PC. If you're not running any software that might have caused this run an anti-virus scan.

Thanks, I think I remember now, I used cheat engine on another game long time ago, but it was uninstalled without a trace. But could it be that some leftover file caused this?

Yeah surely. However, if you ran MTA for a long time with leftover files still on your PC, MTA should've detected it a long time ago and it doesn't make sense that you got banned just now.
Try deleting the files, if not run an anti-virus scan.
