my Windows Defender (Beta 2) has an error?

Question

When scans it comes up with 1 severe/high alert level:1 but cannot remove it because it has an error 0x80501001 I think there is something wrong with computer because it has different pieces of pages and programmes open at once on top of each other. I have no viruses according to Trend Micro PC-cillin. I don't understand computers and need help.

Answer 1

This means Windows Defender found the threat inside an archive. Go to Event Viewer to see what file the threat was found in. If it's in a system restore file, deactivate system restore, run the scan, then reactivate it.
