  1. Defender crashing PC, Security Scan not helpful


    Since last weekends Defender update whenever it runs it blue screens. Tried running Security Scans, both quick and full. Whilst they were running they each flagged that problems were found but at the end stated there were no problems. Not much use.

    Windows defender crash during scan

    Kaspersky picked it up and cleaned it out

    I had something similar a while back.

    I tried un-installing both Defender and MS Security Essentials. Then I scanned the pc direct at Microsoft.
    MS came up clean with no issues found. So I reinstalled both thinking all was good.
    NOT!!!

    Nope, didn't work. I had a nasty virus hidden and the best thing I did was buy Kaspersky PURE 3.0.
    Kaspersky picked it up and cleaned it out.
    And I also bought Malwarebytes which works seamless with Kaspersky.
    I am a believer now.

    I have to thank the MM (mailman) and a few of the guys here at TPU for nudging me in that direction.

    Hi Ian,

    Thanks for posting your query on Microsoft Community.

    This issue might occur if you have set any task scheduler for Windows Defender.

    I suggest you to delete the task for Windows defender and check if it helps.

    Follow the below steps:


    • Search and open Schedule tasks.

    • In the left-hand menu, open the Task Scheduler Library, then select
      Microsoft >Windows >Windows Defender.

    • Double-click Windows Defender Scheduled Scan.

    • Select the Triggers panel, then select Delete.

    Hope it helps, reply to us with the status of your issue. We will be happy to assist you.

    Defender Periodic Scanning or Offline Scanning?

    That link does suggest it's useful to use Defender offline scanning in addition to periodic scanning and a third party real time anti virus (e.g. Kaspersky).
