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.

 

Windows Defender Definition Updates.

Thank you Elba for the prompt reply. However, there is a problem: In "Control Panel" under the "Programs and Features" page > "View Installed Updates" the " Windows Defender Definition Updates" are NOT listed. Consequently, I cannot delete/uninstall them.
The same thing happens when I use "Settings" >" Updates & Security" > "View Update History". Here the Definition Updates are all listed but I can't uninstall them either. Any other suggestions?

Thanks again, Fred
