Hi Guys,
If you use Search feature of the forum with “red circle” keywords you will find the following threads in that chronological order as below
Basically as a latest conclusion given by
But reading those threads don’t miss mentioning presence of another Firewall (FW) in the system by one of the users.
Despite eliminating the presence or leftovers of old FW seems didn’t help as reported or “helped temporarily” – it is still worth checking, because Comodo does not check and notify about presence of other FW including native Windows FW if that one was switched back.
As far as I know you are alerted/advised about another FW only during Installation of Comodo.
