Problems with steam at the launch of the new patch

At the launch of the game on steam, after loading the new patch of the game for an infinite time, the antivirus was activated, signaling zerok as a threat, made me restart the PC and quarantined the file.
I got into the old fashioned game without steam and had no problems. I wanted to report it to you.

Same Here. I disabled my AV when i got this message. 2nd time i opened ZeroK it did not produced the warning.

System:
Win7 Professional
Avast Antivirus
ZeroK Steamversion
