For Your Information: It is possible to leave comments on Symantec's website, but regardless of whether you leave your name/address etc., in the hope of a response, don't hold your breath or keep your fingers crossed, as I doubt they'll care what you have to say or how badly Norton or any of their software companies have treated you. They don't give a damn. I have yet to write them by snail mailwith all the problems I had of their previously excellent Norton 360 gobbling up my maintenance software, from about 8 month ago: having ignored it for the previous 5 years! I have learned from experience that if you have maintenance software that has similar maintenance functions to some of their own (added on over the years) (i.e. not virus related), that they will use their Antivirus software to remove it's executable files and destroy it! Never mind that they had ignored it in the past!
