I am being plagued with the Paltalk promotion box "Visit us at Paltalk" so I deleted the program, but some files would not go.

Despite this deletion the promotions are still coming, and occur even a few seconds apart. I cannot proceed with my computer work until I click the "OK" tab on the promotion box.

I suspect that Paltalk is abusing their knowledge of my email address and I greatly object to this.

How can I stop this illicit intrusion into my life? In my opinion this activity constitutes criminal conduct.
