Both Norton 360 and Windows Defender, enabled and real-time

Other discussions said that only one real-time scanner for infectious file checking can be enabled to be turned on; never more than one active or they cause problems.  I have checked into the settings of Norton 360 and Windows Defender on two different computers, and find that both are operating and no frequent or troublesome problems occur.  Of course, they do not seem to scan at the same time.  They are scheduled to scan for the most part, at different times.  The W.Defender of both is set to once per week at specified time, and the Norton for the one is set either to a different time during the week and the Norton of  the other is set for automatic. 

No problems.  What am I not understanding?

HI g_cafe_c

The issue is the real-time components of AV scanners which can conflict with each other. There is a real-time component in Windows Defender that performs the same function as Auto-protect in Norton 360 and these 2 will try to scan files together and create issues.

You should, at a minimum, disable the real-time setting in Windows Defender but preferably disable it altogether t prevent the possibility of conflicts.

Your quote:- "You should, at a minimum, disable the real-time setting in Windows Defender but preferably disable it altogether to prevent the possibility of conflicts".
"the possibility of conflicts".
How would these conflicts appear to the non-techy ?
Pop-ups, false log entries, product failure.
Any chance of a better explanation ?

Appreciated. AK

Hi photo762

It can lead to program crashes and/or errors in either of the AV programs. Since they are both running realtime they both try to scan a file when it is being accessed and conflicts can and do occur to do with the timing of that.

We have regular posts in th forums from people who have had serious issues on their systems that have been resolved once we get them back to running only one real-time AV product.

Here is a web article to reference

mdturner - On rare occasions, I may have seen possible evidence of such conflicts.  Maybe all such evidence, as rare as they have been, would disappear completely if I were to switch one of the software products to do its scheduled scan at a different time than the other software product, or to usually set one of the products to only scan when manually chosen.  I wish I could remember the messages displayed to me when I found them; like I say, these apparant problems happen so very rarely,  involving Norton 360 liveupdates or Windows updates, or a Windows Defender scan.

Hello g_cafe_c

These conflicts will happen a lot of the time deep inside your computer. Each program installs drivers and other files which will be fighting over who will get to find the file first. You probably won't see the fights going on, but they will be still happening. You won't be getting double protection. It's not just the times when you will be scanning with the products. It's the files that get installed that won't get installed properly and won't be able to function properly either. Live updates happen all the time. Idle quick scans happen all the time. There are funcions of the program that you can't always schedule or control..

Try to look at it this way. You have a bad appendix. You have one doctor operating on you and cutting your whole stomch open to take out the little appendix. At the same time, you have this other doctor who isn't working together with the fisrt doctor, but all he does to take out the appendix is to make a very small incision. So you have 2 doctors who are working independently of each other trying to take out this appendix without killing you and going about it in completely different ways. These 2 doctors are both going to try and get to the appendix first, but there will be problems doing it that way.

Sorry, it I got a little carried away with my description or example, but I think it is something similar with what goes on with 2 programs trying to do the same thing.

Success always occurs in private and failure in full view.

Should I turn off Windows Defender or set it to not scan at  its once per week scheduled time?  My normal new laptop computer has Windows Defender and Norton 360, and I could just run LiveUpdate on it every day or so and choose scans manually (even though the settings might currently be set for once per week).

Hi g_cafe_c

At a minimum you should turn off the real-time element of Windows Defender.

Thanks for the info.

In all the long time I've used Norton, I've only had a couple of alerts, regarding web url's. As a rule, it's sweet as a nut, working in the background.

Windows Defender appears more watchful, flagging-up the occasional file with a potential hazard that requires authenticating.

I am a small user of the WWW. I don't like being chained to my PC.

I wonder in a very small way. How many Norton users are totally happy with the products, because they've never had a reason to Blog/Forum ?

The more you read the Blogs/Forums, the more you wonder about your own PC !

I have a feeling reading Blogs/Forums, at any length, could be counter-productive.

Re: Both Norton 360 and Windows Defender, enabled and real-time

The once per week automatic scheduled scan in my Windows Defender is now turned off.  I have done nothing to turn off any part of Norton 360; it never automatically scans, mostly because I rarely use the computer when that scan is scheduled. Instead, I generally run LiveUpdate after almost every startup, and sometimes do a quickscan; once in a while a full scan.  The Norton 360 autoprotect and the Norton 360 firewall are still turned on. 

I have not seen any settings for "autoprotect" in Windows Defender.  Am I missing something?

(I guess, any response to this question should go in the Other Products forum instead of here)

1st time at being really helpful; so, here goes ?
Open Windows Defender.
Open Tools.
Open Options. (A big page of options)
Real-time Protection Options are about halfway down.
Select the correct options for your requirements. SAVE (bottom-right)
Close back to the desktop.

Well, that's helpful, done for the day !
