In the early years, I was a huge Norton fan. Not only was the anti virus software great, I had two floppies full of tools that Norton developed for troubleshooting both AT and XT IBM clones. Powerful stuff. But then (a bit more than 20 years ago), Norton decided that they needed to make using the computer fool proof. Well as the axiom goes... when you make something fool proof, you end up with only fools using it.

At that point, it became seriously invasive. There wasn't a thing you could do on the computer that it didn't stick its finger into to make it "better" or "safer". I ditched it in favor of Avast!. The free version of Avast!, once I installed it, took about three days running in the background showing me popups of things it found that Norton had missed. My son-in-law turned me on to it. He told me that he had a similar experience when he replace McAfee .
