I know Norton and other antivirus programs are but as this is Windows you can't be without. And as I've paid for it, it will stay.
I'll try to use Edge instead but I've always found IE to be shit compared to Chrome in the past. Perhaps Edge has improved.
I'd hoped Windows would've improved in the 5 years since I had one at home but it doesn't appear to have. Everything is much harder work than on a Mac.
