windows defender antivirus has an error code :- 2147012721 how do I get the virus and spyware back onto Windows defender

Answer 1

Dorothy,

Run <<Disk Cleanup>*>*and delete (at least) Temporary files, Offline webpages and Temporary Internet Files as this will reduce scanning times by security software –clear your cache, cookies, and history, press Ctrl-Shift-Delete – then shut down and restart your computer.

Your computer and the service don't need to have an identical date and time, but if they vary too much it will prevent you from checking for updates. The following steps are the most common solutions for this error code.

First, verify that the time, date/year & time-zone are set correctly

Reboot if you changed any of the above.
