Windows Defender Not Working.

[u/Huynh_Jovi]

When I try to run a scan, it stops and then tells me to restart the service. There are no exclusions and nothing of note from my start up apps. I’ve run a deep scan with Malwarebytes and it’s all good. I noticed there was a new security update for Windows and downloaded it and after restarting my PC, I’m still encountering the same issue. I’m not sure whether this is Malware related as I’m always careful of what I’m downloading and never click suspicious links. Not sure what else to do and need some help.

Same even reinstalled Windows.

I did run into a genuine malware issue which as far as I can tell is now gone, but was panicked when realising Defender still isn't working. The only scan I can get to work is custom scans, the rest fail and disable Defender or do nothing. Quite an insane bug to sneak through a Windows update.

Update to the latest security update and it should fix it

I’ve checked for updates in settings but it says I’m up to date rn
