USB hard drive - can not safely remove


Lately im having this issue. Comodo agent is preventing safe removal of usb drive. I searched the forum a bit, but no solution was given to this problem.

Only way i can force it to safe remove, is to use Unlocker app to free the cmdagent process (see screenshot 1)
The windows event viewer says only that “cmdagent with id xxx has prevented the removal of blah blah blah …” (see screenshot 2)

I have disabled defence+ and sandbox, antivirus on statefull, firewall on safe, no active scaning going on. Comodo cis version is 7.0.317799.4142.
Dont know how to deal with this, help : (
