    Windows Defender Updates and Scans Right After Boot

    Hi Folks:

    I have disabled Automatic Protection, and I have set up update and scan times for Windows Defender, through the Task Scheduler. However, when I login to my desktop, after about two minutes, Windows Defender updates and scans my system. I turn it off and it stops.

    When am I not doing so that this action will be disabled? I update at 2:45 am and scan at 3am, and this works, but why does it need to scan at boot time?

    On the 0x80070002 error, do you have WUS set to auto install updates ?

    Also what do you mean by turning off Windows Defender after the scan at boot ? Defender gives Real Time protection and shouldn't be disabled.

    EDIT: Just noticed the multiple threads here. I was going by Your New MSFN thread.

    No I mean that it's doing a full scan after bootup and I stop that scan manually. It's still working on-access (or in Real-Time Protection).

    I guess no further news on this eh? Just to make sure I'm clear, the Windows Update service is on, but Automatic Updating is off. So I only update Windows Defender either manually, or with Task Scheduler. This error appears to have gone away now that I don't include Windows Defender in Ccleaner, so that's maybe one down.

    But when I boot my system and login to the desktop, after about two minutes, Windows Defender starts scanning my whole system. How can I stop that scan from happening?

My Windows 8.1 PC used to do a full Defender scan in about 8 minutes. A few days ago it wouldn't complete a scan after 13 hours, the progress bar was only like %3 done. I made a thread. Someone suggested scan in safe mode. I didn't do safe mode but I scanned again and after about 15 hours, it...
I've read that you used to be able to go to Tools > Settings in Windows Defender and schedule periodic scans. However, in Windows 8, the Tools menu is gone! I see nothing about this in the Settings section. I've also tried to set this up in Task Scheduler, but I don't know the proper command and...
What's with the Windows Defender Updates? in Windows Updates & Activation
So the first thing I did with Surface Pro 3 was run all the updates. I would actually have to go back to the previous menu, and back into the update section to recheck for updates. All until I could reboot, and there were no more updates available. So ever since then, I have been getting new...
I'm using Windows Defender, and I believe it's causing freezes on my system. What's happening is that I'll notice my system freezing, and I see a little black clock on the notifications flag which says "scheduled scan." If I do almost anything with the computer, it will freeze. If I do a...
