Explorer should not be used. Its like using a waffle house toilet. Microsoft Edge is far better. Its all new code. Its much safer. Its like a self-cleaning porta-potty. Or use Fire Fox. Chrome is the evil empire. (Microsoft is like the old tired evil empire). But Fire fox is pretty good. And they don’t want to take over the world.
I don’t have any trouble with Internet Explorer, and it’s been years since I last got a virus or a bug. I have several anti-virus programs, and they have kept the invaders out.
Symantec Endpoint, Spybot Search & Destroy, Spyware Blaster, and Zone Alarm, plus Malwarebytes in case I do need to remove something. They don’t seem to slow things down much, and they really do the job.
