Hack Tool Has Been Detected (1)(2.0)

So I was playing CF today and i won a 7 days axe. I joined a knife match and i had the game of my life



I made 4 kills in a row in first round and had a a kd of 14/2 after 4 rounds. Well i know there are better players with better kds but i had 1/8 last round so well you know...

As you can think the other players where really ****ed at me and they tried to kick me, and yea it worked. So i was kicked an my and back at the lobby, my score was gone and I'd like to save the replay but couldn't because i got kicked.

Well i sad whatever just join another server but the game was frozen, i couldn't join or leave or go to the storage. And suddenly a popup appears and says: Hack Tool Has Been Detected (1)(2.0)

wtf?! I don't remember the numbers but I think it was 1 and 2.

I was not hacking... Do i have to worry about my account? Because i was not hacking and i'm 100% against all hacker and i don't want to be banned for no reason...
