Battle of the antiviruses

I 'm running Norton Security Suite on Windows 10 (on a 5 year old PC).  A few days ago, I ran Windows Updates, and on rebooting, to my surprise, Windows Defender started running, and between that and Norton, brought my PC to its knees.  I finally got Windows Defender stopped, and put back to bed again, but it wasn't easy -- everything was so slow and locking up.  Be careful out there.  BTW, I did the same update on my (new) laptop, and did not experience similar problems on it.

This appears to only happen when using Windows Insider preview builds.

Re: Battle of the antiviruses

Hello

This is due to a new feature in Windows 10 computers. I think it was part of the Anniversary Update.  Please see this link.

https://blogs.technet.microsoft.com/mmpc/2016/05/26/limited-periodic-scanning-in-windows-10-to-provide-additional-malware-protection/

Norton recommends to turn off this scanner. The above link also tells you how to disable it.

Thanks.

Re: Battle of the antiviruses

PatsSoxBruins -- not using Windows Insider preview builds.  Only the free upgrade to W10 from W7, and the Anniversary Edition update.

floplot -- Don't think so -- I've had the Anniversary Edition for quite a while with no obvious problems. Problem happened on Nov 8, when I installed "Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB3200970)".  Although I turned Defender off, I notice that there is one of the hidden icons in the area above the System Tray (don't know what that area's called) is for MS Defender, and it when I hover over the icon, it says: "PC status:  Windows Defender is OFF".  Don't remember seeing that there before.  BTW, the event started with Defender complaining about my Webcam settings.  This event may have just been a "fluke".

You can easily disable Windows Defender permanently.

Re: Battle of the antiviruses

The Anniversary Update added the Periodic Scanning by Defender even if you have a 3rd party AV installed. If you check your Win 10 Settings for Updates and Security, the Defender tab will tell you if you have Defender on or not. If you see Defender is off, but the Periodic Scanning is on, that is the explanation for why Defender was running a scan.

This may just be the first time it has run on your system, or it may just be the first time you have noticed it.

Hello

That is what I suggested it was. My link described that new feature and I said it was part of the AU, but the O/P said no when I pointed it out. The site even had the same screenshot about it.

https://blogs.technet.microsoft.com/mmpc/2016/05/26/limited-periodic-scanning-in-windows-10-to-provide-additional-malware-protection/

The name of the link shows it is the same topic as already mentioned by me. I guess my site wasn't looked at..

Thanks.

Re: Battle of the antiviruses

so is it ok to have that enabled if one is using Norton Internet Security?

That is your choice but Symantec do not recommend leaving LPS enabled.

We do not recommend enabling Windows Defender's periodic scanning feature on a Windows 10 system running Norton. Periodic scanning is redundant and will require unnecessary additional power consumption and may result in conflicting notifications and messaging.

Re: Battle of the antiviruses

ok cool so I'll just follow the instructions to NOT let it periodically run ( I am assuming from what I read that I can Keep it from being on?)

Also, how do I know if I have the windows 10 anniversary update?

g_arm:  Also, how do I know if I have the windows 10 anniversary update?

The anniversary update should show the version number "1607" which is the year and month of the release (July 2016 - this is not August despite the update only being available on or after the 2nd of August presumably because the version was initially released to Windows Insiders in July for testing before the final release).

Press Windows key + R on your keyboard
Type: winver
Hit Enter
Version 1607

Re: Battle of the antiviruses

I followed the link PatsSoxBruins provided above.  I used the Registry editor method, and it worked -- got rid of the Defender icon too.  The article didn't specify whether to use a decimal or hexidecimal value for the key, so I used decimal -- I guess a 1 is a 1 in either system.
