I let Norton expire and added Avast. The very first
act done by Avast was to ask me if I wanted to delete Norton Safe Search from my Chrome add-ons, because it was identified as a program that had a "bad reputation"
(actual words) amongst Avast users. It said that this add-on could allow for vulnerabilities.
I just thought it was funny that Avast went after a Norton product as its first order of business. haha!
