Hi,
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?
Thanks.
