After a failed Safe Mode / Restore to previous date (was finally able to do it on regular windows boot but not in Safe Mode), my security shield icon went missing so I put it back - but when I tried to run a scan by right-click/Run Quick Scan it says:
Your IT administrator has limited access to some areas of this app, and the item you tried to access is not available. Contact IT helpdesk for more information.
I don't have an IT administrator/helpdesk. Just me and my single laptop.
It won't update the latest definition, either. Gets to 100% installed then slings an error at me. (0x80070643)
I was able to start a scan by going to windows icon / settings / windows security / Virus and Threat Protection, but it just sits there and won't begin the scan.
When looking up version/build info (Settings/System/About), the Virus and Threat Protection has a BLACK DOT instead of a green check.
Also, isn't Virus and Threat Protection supposed to be listed in the main window when I click the shield? It isn't. What's wrong with it? What in the world have I done??? I can't figure out how to fix this.
Please advise and thank you.
