Windows Defender Won't Start After Upgrade To Windows 10 & Spybot Install

[lwdaddio]

So much for that idea. When I try to run it in Windows 10, I get a stream of errors about access violations at address 000000000 <sigh>.

Mea culpa! I installed into a folder that used to have V2 in it and didn't clear the folder first. After I deleted it and reinstalled, it's scanning okay now. Sorry 'bout that :-)

This is an issue with Windows Defender. Windows disables this program if it detects another internet security
program on your PC.

You can avoid this issue with Spybot by following the instructions below.


Please go to:
Start Center > Settings (tick "Advanced User Mode" if you do not see "Settings") > System Integration

Here, uninstall the Windows Explorer Integration feature.

Click "Apply" and "OK", and reboot your PC.


When it restarts, Windows Defender should be running normally.

Had the same issue and got into a loop of reinstall of Spybot. Deleted file directories and maybe I am ok. Does not like Defender at all.

I will try the above next week end.

Thanks for the excellent help.

Thanks for the info. Unfortunately, followed the above and it doesn't seem to work. Also relaunched Start Center upon reboot to confirm that 32 and 64 bit Windows Explorer Integration was uninstalled, and they were.

Found a fix that worked for me on another thread.

Go to Start Center -> Settings (check "Advanced User Mode" if you don't see Settings and it should appear) -> System Services tab and uncheck "Activate after every reboot" under "Security Center Service" and click stop for "Security Center Service" as well. Then hit "Apply" and "OK" and you're done!

This makes sure that Windows Security Center doesn't recognize Spybot as a security program, so it doesn't stop Windows Defender due to the supposed duplication (at least if you only have the free version without the antivirus options; if you do have those features, it may actually be best to leave Defender disabled).

This works. Maybe good to add, you have to change the services settings within Spybot itself, not within windows.
