Pretty self explanatory with this one. Play on a server for a bit, do pretty well, suddenly get disconnected with this message; “You were kicked for a security violation” and a link to the nexon page for inquiries, then the whole game shuts off. I seem to remember this happening a lot when the new security thingo was first implemented but now it just happened 5 consecutive times.
What causes this to be tripped, if it’s an actually intended part of the security system, would it just check for weird programs running in the background while you’re doing well in a game? Because the only thing that’s changed is i’ve been using Discord rather than Mumble 
[Crash Bug] - "You were kicked for a security violation"
Yeah, i cannot get a single game right now without this error booting me after a couple minutes. Verified the game cache in steam to see if that helped, said that there were 2 missing files and they would be downloaded. Do that, fire it up again with no change. Verify again and comes up with the same problem, as if nothing was downloaded. Restarted steam completely too with no changes either. Additionally while i’m in a match before i get booted, it seems to not allow me to get any of the new Steam achievements either (like the one for healing or reviving people), as if the game isn’t talking to DB servers properly.

Not sure why it keeps happening to you though, make sure no antivirus is blocking the anticheat or anything, I dunno
