Pop-Up "Norton" Ad
Even though I have "Special Offer Notification" set to "off", a little while ago I had a pop-up ad appear for a game "from the creators of Norton Internet Security" or something like that. (Unfortunately, I closed it before paying attention to exactly what it said.) I'm running NIS 126.96.36.199. After the pop-up appeared, I ran scan with both NIS and Malwarebytes--both came back clean.
Any idea what this was and why it happened?
