Every so often, sometimes every 25 seconds, an alert dialog pops up warning about a virus on my computer. Sometimes, not always, McAfee appears to be the source. But McAfee is not installed. Or any other anti-virus software. (outside of the standard Microsoft stuff)
I visited: Settings -> virus & threat protection, and under “Virus & threat protection settings” is the text: “No action needed.” Regardless, I opened “Manage settings” and everything in there was turned on.
Side note: In the images posted, note that the captured image is larger than the actual information dialog. When a snip is in progress, and the cursor gets closer to that dialog, clicking the mouse to start the rectangular snip dismissed the dialog. Wait! What?? Yes, that happens. I thought something was wrong with the Microsoft built in snipping utility.
Are these valid alerts? If so, what action is needed?
How can I find the origin of these messages and stop them?
