Several Redditors have reported MD not working after the latest update


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.

Haha, my quick scan will be bogged today, but tomorrow is another day. Meanwhile, I promise to not download any malware.

Microsoft totally breaks Windows Defender virus scans in trying to fix a 0-day flaw

Microsoft Defender is failing to complete quick scans, full scans as well as offline scans after recent updates.

Recently, security researcher NightmareEclipse managed to point out a major issue with a Defender patch that could allow threat actors to completely fill up the disk space. The researcher recently released another LPE proof-of-concept dubbed "ShieldBreak".

However, in trying to patch this zero-day, Microsoft, it seems, has broken Defender scans as users are reporting they are unable to complete virus and malware scans on their systems. Both quick scans and full system scans seem to be affected with several users on Reddit reporting similar problems after installing the latest Windows security update.
