I got a popup that said Windows Defender had an error code. Call 800 for Microsoft Certified tech.
I called and they wanted $300 to clean my computer. Told me I had a "memory leak" I told her I had Norton on my system for protection and she said that was the problem.
I finally told her to disconnect and that I would call Norton.
Norton scanned my computer, no issues and they got the popup removed from my screen
Reason of review: Pricing issue.
