The worst program I have ever had to deal with Norton 360. I can't even uninstall it

Despite the total loss of my investment cost, I can't even delete all the tentacles of this insidious program.  I had to drop back to Avast to have some coverage while I tried in vein to contact Norton.  I freakin hate this company. They get your money up front and then turn you over to help from the other side of the globe.  I have a sinking feeling this is going to trash my pc ultimately and then I will have to buy another pc that I can't afford.  I am a disabled senior living on SS and I needed security for my computer.  I put my trust and much of my disposable income into what I thought was a good investment   I already know I lost my $60 dollar purchase price for vaporware.  Now all I what is for Norton is to remove all remnants of its insidious program from my Win 10PC  Norton 360 ex user, never used will never use
