Keep getting kicked for this issue also. I tried disabling the steam overlay and running different mercs but nothing has worked so far. I can get a couple of rounds of execution in before it kicks me.
Also, this hasn’t happened to me before today’s update.
**UPDATE: A system restart seems to have solved the issue for me.
haven’t been able to play in days since this issue started happening to me, I get kicked every time after only a couple of minutes, nothing seems to fix this issue for me 
hope this gets resolved soon I’ve been waiting days and still no clear solution if there’s something more I could do on my end…
Try verifying your game files. I did that, followed by a restart of my pc, and it seemed to clear it up.
Same problem with me too after recent update. Before update it was working butter smooth with 0 crash. I even tried closing all unwanted process, services, schedule task & removing drivers, tried disabling ESET Smart Security AV realtime protection & firewall & even tried disabling it service & played without AV but stills don’t work. I verified game cache more then 10 times, defrag my HD, scan my pc for malware, tried different mercs & cards on them, restart steam & PC… but sigh nothing works. What i see that after i get security violation error, Nexon anticheat crashed & it’s process stays open with 30-40 % cpu consumption.

Same thing is happening to me, including the cpu consumption after it crashes.
It’s really annoying and it happens A LOT, I basically can’t play anymore.
I think SD needs to take this problem seriously and fix something on your part, I think it’s clear that last update broke something.
Nvm, the violation keeps coming up even after verifying files and doing a restart.
Just now got kicked for it while in a pre-game lobby…
Please, fix this, for the love of me. This is really unfun when I need to restart my PC every 3-4 matches. Especially when I play with my mates.
I was randomly kicked in my first or second match in the game. I dunno why. Silly.
This just started happening to me tonight. Every single game I am kicked for this. If I join a game half way over I get kicked when we are in the lobby.
Is there a fix for this yet? I can’t get through one match without being kicked.
Its been happening since the update i get kicked after 10 minutes of opening the game if i am in game or not
After 16th june fine tuning dirty bomb kick me out for security" violations
Just get rid of the antihack. Its been going on for over a year now. Do us all a favor and get a new one.
