Windows 10 Update Error: " Definition Update for Windows Defender - KB2267602 (Definition 1.213.1379.0) - Error 0x80070643"

Hi,

I have a laptop running Windows 10 Pro TH2 that was upgraded from TH1. Once Norton 360 is installed, Windows Update does not work properly and always shows error "Definition Update for Windows Defender - KB2267602 (Definition 1.213.1379.0) - Error 0x80070643". Once I uninstall Norton 360, Windows Update then returns to normal. 

I have another laptop running Windows 10 Pro TH2 that was upgraded from Windows 7 and does not have such issue. It seems that the Norton 360 Setup does not disable the Windows Defender properly for one machine but does for another. What can I do to solve it? Thank you.

I also have the same Widows Defender error issue, it has been weeks now, is Norton going to push a fix soon?  I cannot keep my computer up to date until this error is cleared.  Thanks.

I have exactly the same problem (Norton Internet Security on a win10 home i7 desktop). Tried to turn Norton off during installation - didn't help. I then uninstalled the entire antivirus software, run the windows update and the Win Defender definitions were nicely installed :-). Finally I reinstalled Internet Security. It lasted a few days until a new definition package were released, and now I'm back on square one... The described operation clearly indicates this is a Norton issue, would really appreciate viable solution.

Definition Update for Windows Defender - KB2267602 (Definition 1.213.2822.0) - Error 0x80070643 (on latest cumulative Windows 10 update)

I suppose to update Windows Defender definitions Defender should be running, but Norton Antivirus does not allow Defender to run. Do we have a circular dependence here? If so, Norton cannot solve the problem alone.

Has Microsoft made a small mistake here? They allow other anti virus software to run and Defender gets disabled but then Defender cannot be updated during Windows Update.

Who will step back? Norton is big but Microsoft is huge ;)

This problem has happened on two  of my devices running Windows 10 Version 1511 Build 10586.63 on which I installed Norton Security after Windows Defender had been installed by default. Defender cannot be removed and it should stay there to take over when a third party antivirus product is removed.

I tried to resolve this problem by going through several time consuming steps typically taken when the Windows Update store is corrupt (sfc, repair Windows update) but that doesnt make the problem go away.

Only one solution has worked so far: uninstall Norton, let the Defender update run then reinstall Norton. This is very time consuming and annoying. Obviously, Norton blocks the defender update and this leaves Windows update in a defective state. I hope that a solution between Microsoft and Norton can be found. After all, I have been paying money for Norton products instead of using the free alternatives in the hope that problems would be addressed in a professional and speedy way.

What  P Mossel  found about uninstalling Norton to get the Defender update has worked for me with this issue.

One thing to add, before reinstalling Norton, go to Windows Security settings and turn off Windows defender manually. Then install Norton.

One thing to note. This is really more of a cosmetic issue, as Defender is actually disabled anyway. So it does not matter if the updates fail. This issue still allows all other Windows updates to complete.

Good point about defender being disabled anyway. Obviously, blocking other (security) updates is a serious matter.

Further to peterweb's comments, Davec33 posted instructions in the thread Windows 10 update stopped because Nortons Security turns off Windows Defender for disabling Windows Defender's real-time protection in while Norton is temporarily uninstalled.

The only caveat is that users should remember to confirm that Windows Defender's real-time protection is re-enabled and protecting your system if you decide to permanently remove Norton at some point in the future.

I actually got my problem fixed yesterday :-) 
1. Inactivate Norton Smart Firewall and Auto Protect
2. Reboot
3. Open Windows Defender an turn it on (couldn't do that when Norton was active and prior to reboot)
4. Run Windows Update -> Defender definitions were successfully installed
5. Reboot
6. Turn on Norton Smart Firewall and Auto Protect

I now expected that this should be OK until the next Defender definitions update (but the procedure above is at least much less time consuming than make a full uninstall/reinstall every time). BUT suddenly I couldn't open Defender anymore, only having a message saying that Defender has been inactivated and no longer protect this computer. This is good I think, because that is EXACTLY how it looks on my laptop (win10 and same Norton version as my desktop) and on that computer I have never seen this problem. So my guess is that now its running the way it's supposed to.

Yes, you nailed it. Turning these two features of Norton off, run defender and restore Norton's settings allows the Windows updates to go through. Thanks. I retract my suggestion to uninstall and reinstall Norton as it is too drastic.

Interesting that just disabling Norton Firewall and Autoprotect worked for you. I just tried this on Win 10 Pro, with Norton Security Premium and after disabling the two Norton features I was still not able to enable Windows Defender.

All the above offers are not solving the problem but trying to somehow "get around" the problem.

Decision can only be a situation where the developer of NIS and N360 apps will release a new versions of the installer correctly disable the corresponding registry entries and as a result - Windows Update service will stop trying to get current updates for Defender disabled.

Perhaps many will continue reading in these topics:

It could also be that Microsoft has messed something up with the way Defender is supposed to be turned off. Norton may be using the correct APIs that should do the job, but MS is not reading it properly.

Win 10 is still a work in progress. There were earlier issues where the Security Center kept reporting, incorrectly, that there was no malware protection on our systems. That was fixed with a later MS Update.

Hi peterweb:

I understood that the earlier problem described in the support article Windows Action Center incorrectly reports that my Norton product is turned off or there is no antivirus program installed was identified as a Norton v22.x bug that was patched with the latest v22.5.5.15 update (see Tony Weiss' announcement Norton 22.5.5 Product Update available now).

Perhaps the v22.5.5.15 update solved one problem with the Windows Action Center but inadvertently created a new issue where Windows Defender real-time protection is not disabled correctly in the Windows registry after this v22.5.5.15 patch is applied on some Win 10 systems.

Disabling Norton Firewall and Autoprotect, did at first not work for me either, but doing this followed by a reboot did the trick. However after having the updates installed i noticed that Defender turned itself off again without my involvement getting me to think that I was in some kind of race condition with a backround process. I then never got it to turn on again and that's why I made a second reboot just to check if the process could be repeated. After this second reboot I discovered that Defender seemed permanently inactivated (I guess now Norton have full control of the protection as it's supposed to) as you can see in the screen-dump below. Sorry for the Swedish. 
Even if this last part never occur (maybe I was lucky) but you can outrun the internal process locking the Defender on-switch I guess it's still a much faster workaround than making the full uninstall/reinstall-process.

Did you do this just after installing Norton and before a restart of your system? That might explain what happened, If Norton was not yet fully installed, you may have still had access to Defender.

If you can get it to work, it is much quicker and less cumbersome a fix.

I did the Norton (re-)installation a week back so I would hardly think that this was the case.
I'm sorry this workaround didn't work for you, I really thought I had it this time...

Peter, I agree with you absolutely.

I can only repeat once again my naive question which I have asked on the MS Answers

"Developers from MS and developers from other companies (manufacturers of AV products) have the right to maintain official normal working relationships with each other?"

Hi,

for tihis problem in my TH2 allupdated and NIS allupdated I've started windows defender (start now red button) and after few seconds the windows defender result as disable. In this situation the windows updates for defender are hidden from windows updates list.

Same solution I've adopted for NS on another laptop.

Lucky you!

Tried the same on mine and no luck :(.

Tried the update on two other windows 10 machines both with Norton 360 and all is fine.

There must be something different on the failing machine.

Well yes--the failing machine is different in one obvious way--it runs and SSD that contains the bare minimum of what's normally on a C drive with all the remaining temp and user directories on a separate drive.

Could the defender installation be depending on the traditional single C drive installation?

OK. Another attempt to solve this nagging problem as of Feb 2016. This time on a new computer that never ran Norton.

Problem: Windows Update is blocked on W10 because it tried to update Windows Defender definitions and defender is turned off by Norton. When running defender (it runs!) it will not let you update the definitions through Defender.

If Norton is installed:

  • Turn off Norton real-time: disable auto protect and disable smart firewall for 1 hour (and work quickly!)
  • Reboot!
  • Try to run Windows update. still no luck.
  • Turn Norton real-time protections back on (Fix Now)
  • Invoke Defender. Defender should not run. A message should state that Defender is disabled because another program is managing the defense against the dark forces.
  • Once Windows 10 is convinced that the tasks of Defender are legitimately taken over by another product (Norton) it will no longer try to update the definitions. And Windows 10 will say "no updates", or, at least no updates concerning defender.

So, in addition to what I wrote earlier, the message that Windows Defender is not running (and can't run) ensures that Windows Update will work and that it is safe to turn Norton back on.

Used Campione suggestion, worked first time. disable Norton, reboot, turn on windows defender, update windows 10 then turn Norton back on after successful update. Defender gets turned back off by Norton.

Thanks Camione, it has been bugging me for weeks but didn't stop me updating or installing the firmware upgrade on my surfacebook but was a nuisance.

This will only work if you have Windows 10 PRO.

Windows key - R.  run gpedit.msc.  Thats the group policy editor.

Local Computer Policy\Computer Configuration\Administrative Templates\Windows Components\Windows Defender

Enable the entry "Turn off Windows Defender"

Sorry. I don't know how to do this using Windows 10 HOME

Greetings all,

I just put my first Windows 10 computer into service late last week (an i7-based desktop running Windows 10 Home and Norton 360) and I've already had to uninstall and reinstall Norton 360 twice to correct this exact problem. 

Thanks for the work around suggestions I've found here.  I will set my Windows Updater to prompt me rather than automatically run, then try turning off the Norton Smart Firewall and Auto Protect before running the next Windows update.  Hopefully this will be a little less time consuming.

However, this seems to be pretty wide-spread issue... may we please have some Symantec representation here?

I have a Windows 10 IE11 notebook. The Norton tech (from chat function) uninstalled my Norton Security Backup and ran Windows update until this error message disappeared "• Definition Update for Windows Defender - KB2267602 (Definition 1.215.2092.0) - Error 0x80070643"

He reinstalled my NIS and the error message disappeared. Now it is back after my notebook did its periodic Windows update. Any suggestions? Thanks!

If you look at the post above by P Mossel, and my following post you will see that what worked for me was the uninstall of Norton, updating Defender. Then before the reinstall of Norton, go to the Win 10 Security settings and turn off all Defender settings. Restart your system and then reinstall your Norton.

Hi, just wanted to say I have a desktop running 10 Pro and a laptop running 10 Home.

Both experienced the issue described here, and both were solved using good advice from this page.

10 Pro took 1 min using gp policy edit from robert.alexander1945. Worked like a charm.

10 Home was solved with Campione solution, no need to uninstall Norton (!), except I had to reboot twice (step 2) until Windows told me I could not access Defender anymore as it was no longer in charge of protecting the system (rough translation from French).

Hope this helps!

This fix did the trick for me. (See P Mossel) Defender started up, loaded the definition then displayed an error message similar to when my Norton settings were enabled....BUT the definition update has not returned after I returned Norton settings. So far so good. Thanks...Good forum.
