Windows Defender running a scan at every startup.
I have been running windows 8 pro for the last couple of months. It is
fully updated, and has been running very well. All of a sudden at every startup, when I go to the windows desktop, the disk activity is high, keyboard and mouse response is very slow or non-existant. Starting task manager shows antimalware scan using approx 30% of processor. How can I stop this scan from running at every startup? |

I have tried disabling Defender and disabling the scheduled task for the scan, but the problem continues on every boot or reboot. |

A little more followup information: After a cold boot or a reboot, when switching to the desktop, no Icons appear and the little spinning ring continuously spins. The mouse cursor can be moved but mouse clicks appear to be unresponsive. Continuous right clicking on the task bar will eventually give me the option of opening the task manager. The "antimalware service executable" is using the lions share of the processor. Once I can start task manager, the icons appear and the system seen to resume to normal. I have tried disabling Windows Defender and disabling the scheduled task for antimalware scanning, with no joy. |

Hi, Mike. The last time my mouse behaved like that...it needed fresh batteries. No, not a joke. And it probably is not your problem. But sometimes it's easy to overlook the simple things.

As this problem has recently started it may be something other than Defender that's causing the slow-down. To change the scan at boot up go into Services and in the Windows Defender Service try changing the 'Startup type' to Automatic(delayed) to see if that changes anything. |

Under Tools | Options should be your settings. I do not disagree with Download-latest then Uninstall/[reboot]/Reinstall. Usually fixes just about anything. Haven't heard of WinDef issues in Win8. Sounds like you may have inadvertantly shut-down during an update or WinDef process which could cause this type of corruption. Windows 8 is sort of unique IMLTHO to previous flavors of Microsoft in its update procedures. Many times I get a lag before I get a dialog on screen that essentially informs me "do not shut down; windows is updating" and then no subsequent progress bar... But for the Grace of God, I might have looked away from this flashed message and then been in some similar circumstances. -- I AM Bucky Breeder, (*(^; and That which does not kill you might give you the Pinto Bean Farts, which could kill everybody else, but you'll be OK in a couple of hours - or just take some Tums or Rolaids... then, it's up to the CDC to sort out the carnage.
