A number of times now an unwanted popup has appeared at startup. It says it is from "Noton" [sic] and it has the Norton trademarks as well as a rather odd-looking version of the Google Chrome symbol. The message tells me I am being given a limited time offer to download a Norton purchase protection program worth $1000 guarantee. If by some chance this is legitimate, the presentation needs to be improved. Also, if it is legitimate, I will seriously consider looking for new security software. Is it legitimate? Creepy.
