Problem with Internet Security on MacOS


I've had Internet Security installed on my old iMac, running High Sierra 10.13.6, for quite a while and hardly had any problems with it.

But recently, it stopped functionning. I'll get a grayed out icon with the error triangle in the menu bar and if I try to open it, it starts opening and quits unexpectedly. I could not uninstall it either. So, I downloaded again the version available through my ISP and installed it again, the software asked me if I wanted to suppress the old one and I clicked yes.

For the first day, I ran smoothly. I checked all of the security options and ran a thorough scan of my HDs. No problems were found so I thought the problem was solved.

But today, it started acting again and I can't open it. Any ideas what might be causing this?

Hi @phyl 

As you are running in 10.13.6 OS version, the cause might be due to an  environmental issue on macOS. Please check the below link that has information on this and how to resolve the issue.
