Comodo HIPS high CPU usage

Have been installed Comodo Firewall 6.3.297838.2953, HIPS is in safe mode. When HIPS detects some activity, and asks me for allow or deny, when i press allow, CPU usage of 1 core become to 100% for 10-15 sec, only after that time i could work with software, which was blocked by HIPS. It’s really annoying. Is it “normal”?

It’s not “normal”. Do you have any other security software on this system? 88)

No, nothing. There was a previous old version of Comodo, i removed it and then i install the newest one.

Please try reinstalling by following the advice I give in this topic and see if the problem continues.

Thanks.
