NIS 2009 shutting off Windows Defender

TooStrong — Fri, 20 Mar 2009 03:50:14 GMT

I just received the updates to my NIS 2009 from 16.2to 16.5. when I rebooted NIS shut off Windows Defender( I assume by default, just like it did when I first downloaded NIS 2009 back in October) I like to keep this running so I turned it back on. Then I shut down my computer and restarted it. about 2 minutes after everything booted up A windows screen came up and said windows defender is turned off. I restarted Windows Defender and then shut down the computer again. Then I restarted and the same thing happened again. Windows defender shut down. Is Windows Defender not compatible with NIS 2009 anymore? Is anybody else having this problem?

As far as i know, NO antivirus is compatible with other realtime products. Norton Internet Security Disables Windows Defender due to Realtime scanning incompatibility. If you really want another realtime spyware scanner i would recommend Threatfire. Threatfire doesn't scan the file but looks at it's behaviours and if it is a virus it will notice and quarantine it. Give it a try and look a bit at their homepage "www.threatfire.com".

Btw, im using this myself and i think it is a great tool. It catches infections that not even NIS does :D.

TooStrong ... I am also having this problem and it seems to have just started happening within the last week or so. Unless there is a good reason not to, I'd like to have Defender running alonhgside NIS and up until the last week that seemed to work automatically.

This is nothing to do with incompatability as Defender worked quite happily alongside NIS until latest patch. Now Defender cannot run properly even with realtime protection switched off, as the service is being stopped by NIS.

I have the same problem. I like to use the Software Explorer in Windows Defender and it used to work nicely without any problems with NIS. The latest patch seems to be stopping the service.

I've been able to replicate the problem on two pc's. If Symantec is going to disable Defender (they both worked fine), it would be an nice idea to have the user notified that your turning off an application.

Up until the update to 16.5.0.135 my NIS 2009 and Windows Defender worked fine together. I hope they change it back, because I also liked the extra stuff that windows defender had. Thanks for all the replies, to let me know I wasn't the only one having this issue.

Does anyone know if or what the workaround is to keep both Defender & NIS running? Seems like everytime I turn my PC off and then turn it back on, Defender is once again disabled.

I'd like to add my voice of disagreement with this policy, if it is indeed enforced by Symantec.

Furthermore, it is puzzling that Windows Defender runs alongside NIS 16.5 on the system with Win XP, but not the one with Vista Business. What's the difference, if I may ask?

Interesting add-on product for AV suites... however, doesn't NIS 2009 include the functionality of Norton AntiBot, which would be a redundant (and possibly conflicting) feature?

Best Wishes,

I have four PC's in my home. If your remember last week when Norton did two updates. One was 2 megs (3 files). The next was 13 megs (1 file). Ever since that 13meg file, Defender has shut down. According to the Norton History, it was just the Antivirus Definitions. Why would this effect Defender? I have no clue. I thought the problem was on the MS side. However, there has been two updates since then and the problem still persists. So, I agree with you. Norton is shutting down Defender which could cause problems between the two companies. :robotsurprised:

Hi there,

We looked into this issue and as you suspected, this is a defect introduced in NIS 16.5 and N360v3. We will keep you posted as soon as we have an ETA for the fix.

If I can add to the confusion, I am running NIS 2009 ver 16.5.0.135 and Defender ver 1.1.1593.0 on a Windows XP Media Center Edition ver 5.1 SP3, and it looks like they are both running just fine? Defender runs its daily scans and NIS runs its Idle and weekly Scans. I haven't noticed any problems with either of them. Just lucky, I guess..

You are lucky indeed! :-)

The issue is for VISTA SP1 users.

Well that's weird, N 360v3 and Vista SP1 on my system, and Windows Defender is running just fine.

Oops!! :smileysad: I didn't realize it was a VISTA only problem.. :smileytongue:

I have been trying to see how the Norton upgrade has caused this issue with Defender. I have looked in the Registry. Fine. MsConfig, Fine. Startup application-modified- both programs are there and are supposed to start upon boot. However do this. Boot up, open Defender and just watch your screen. Everything is hunkee-dorey for about thirty seconds (after all applications have loaded). Then the message you see in Defender, is "an error has occured and the program must be shut down." Then go to Computer management (control panel administration tools). The error is NOT recorded. It is as windows is not seeing it.
