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.
Right, you don’t need all that stuff if you get a good browser. Explorer has so many holes in it they will never keep it keen of viruses. But Edge or Firefox don’t get them. Or at least I haven’t had one in 2 years. If they get one. They detect it and repair it before you even notice it.
