I was seeing strange popup advertisements on sites like Amazon and others and was scratching my head until I realized that my young daughter installed "Arcade Yum" on my desktop. They have an uninstaller (which I ran with trepidation), which did not work. Still seeing the popups.
I looked at my Norton Antivirus subscription, which is active and live and current as of this morning's scan and Norton saw nothing.
So now I need to rethink my daughter's screen time and also whether Norton is useful at all...
Any suggestions?
