Three things happen. First a little flag slides in to the screen from the right edge (over whatever I have on my monitor) and says words to the effect..."Your virus protection is off." It happens fast before I can copy the exact words, and then slides back off the screen.
If I then left click the little icon, on the screen bottom, immediately to the left of the time and date in the right corner, a whole panel slides on to the screen from the right side, with heading at the top - ACTION CENTER. There is a message below whose exact words were -
Check virus protection 9:44p
V
Windows Defender and Webroot Secure
If I left click on this message, I'm taken to a Security and Maintenance Page, where via drop downs I can confirm that that my protection software is indeed turned ON.
I am using Windows Defender and Webroot SecureAnywhere.
The Win 10 panel is not trying to sell me anything, or get me to down load anything. This is the same panel on which "hot" news headlines appear from time to time, and on which it invites me to try OFFICE. While OFFICE came in Win 10 I don't use it, never bought it, and have never wanted any version of OFFICE.
Either Defender or Webroot will run full scans indicating no problems found.
