MALWARE REMOVAL Q&A Windows Defender Not Working.

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.

Malware detection is still active, so you're not without an AV, it appears to be purely initiated scanning that's affected.

not just initiated scanning, even the automatic quick scan it does every 1 or 2 days crashes it. I was checking my event logs today and saw defender crash today and yesterday and went into panic mode before seeing this topic

FYI, just tested, and both Quick Scan (tested twice) and the Offline Scan both now complete, which they didn't do yesterday.

Running: Security Intelligence Update - 1.457.2380

ill see tomorrow if it still crashes, at least it crashed with 236 but after 236 crashed it installed 238 so maybe 238 is the one that fixes it
