update for windows 10

NORTON INTERNET SECURITY - "INSTALL AN UPDATED VERSION OF YOUR NORTON PRODUCT FOR WINDOWS 10" and "NORTON DOWNLOAD MANAGER" keeps coming up on screen every 10 mins or so.... i have tried everything i can think of to get rid of this crap and nothing works... task manger / process's finding file location ending the tree and then deleting from file location, deleting temp files and downloaded files, i even downloaded the "NORTON REMOVAL TOOL" and nope this crap still keeps coming up on my screen every 10 mins or so. so i have also tried the "Norton Power Eraser" and nope still same problem with this crap coming up on my screen every 10 mins or so... its very annoying

how do i get rid of this crap permantly..?????

especially since i don't even have any norton software running on this pc

currently running AVG, Zonealarm and Advanced Systemcare and they will not get rid of this crap.....
