Windows 10: Antivirus is out of date and wont update.

I get a notification each time I startup, saying antivirus is out of date, a repeat of the same earlier problem, which I thought was fixed. Try to update each time, but no luck: 'protection definition failed'. Windows 10 and office 365. Can anyone help please? Thanks, Pete

definition update for windows denfender antivirus

Hi mknic,
I have literally just installed the definition update KB2267602 without any problem. I suggest as a first step checking all the Windows Defender settings to make sure they all have the 'green ticks' in each section.






ps. The only reason the 'Family Options' is not ticked is because I am the only user on my computer.

I also would suggest running the 'Troubleshoot' feature in the Update & Security settings which has a section dealing with update problems.
