Getting a Norton antivirus popup only on here. Don't have Norton.
How long have you been seeing it, and are you still seeing it?
I would say it's a bad ad, but if you're the only one seeing it I tend to lean towards it being a setting on your computer. And that popup is from Windows, not Norton.
If you haven't done so already, try this.
1. Clear your browsing history (cache, history and cookies).
2. Close all open tabs in your browser.
3. Close your browser.
4. Re-boot your computer.
5. Open your browser and log back in to SVTPerformance. See if the problem is gone.
MacAfee now popping up as well
