There is a dialog box that appears asking for permission for a program to insert itself
There is a dialog box that appears, regularly asking for permission for a program "Tituricsec" to insert itself. Of course, I don't click "Allow". I figure it's malware.
I searched for Tituricsec to attempt to delete it.
I can find Tituricsec files in my Library folder - but as soon as I delete them, they come back.
I am not a sophisticated Mac user. How does someone like me rid themselves of this malware? Do I go to the Apple store and ask for help? Hire a consultant/techie-kind of guy? Or take my Mac to a computer repair store? Purchase a virus & malware scrubber? - and if so, which one? There are zillions out there.
This is beyond my ability to handle.
So, now what?
Thanks, in advance, for your advice.
