Recently, ZoneAlarm blocked one of the programs I was using. So, to solve the problem, I tried to go and un-block it manually in ZoneAlarm interface.
But, it acts in a pretty strange way... I cannot open the ZoneAlram window. The protection is on, but there's no way I can open it. ZoneAlarm is the only program who is deficient in that way on my computer, and this cannot be caused by a malware of any kind since I just made an A1 clean on my computer by an informatic technician.
Could it be caused by a deficient version of ZoneAlarm?
