Defender keeps turning off

[kls01]

I am having the same problem as other people. Defender keeps turning off
every time I reboot. My OS is Vista and I am running Norton's Antivirus
2009. I have gone through numerous threads, but it seems that no one is
coming up with a solution. I would greatly appreciate any help on this.

Hello "kls01",

Are you sure the system is clean?

A very good antimalwaÑe app is SUPERAntiSpyware.
There is a free version (on demand scanning only), the
paid for version includes active monitoring, similar to
Windows defender:
<http://www.superantispyware.com/>

Try Ñunning Malwarebytes Anti-Malware... download,
update, and perform a quick system scan:
<http://www.malwarebytes.org/roguenet.php?id=401>

Knowing what other Real Time Protection programs, etc? you're running
would help though: like Onecare

Error message when you start Windows Defender: "Windows Defender is turned
off"
<http://support.microsoft.com/?kbid=932902>
-=-

Go here: Microsoft Malware Protection Center
<http://www.microsoft.com/security/portal/default.aspx>

Save it, close all windows/progÑams open, and run as admin.

Click the link in the right frame under ' Latest Definition Updates '
for either the x86 [32 bit] or x64 [64 bit] edition of Windows installed.
*Save* the definitions that will now download.
Once the download completes close all open programs and browseÑs.
Now run the downloaded file [ if the edition of Windows is Vista, then
*Ñight* click it and choose 'Run as administrator'. Follow the prompts
to allow it to run ].

See if that both brings you up to date, and perhaps improves on the behavior
in future.

I am also having this problem, running Vista and Norton Internet Security.
None of the posted solutions worked or apply to my system. Any other
recommendations?

Hi "kls01",

Herer is the full post from Dave M,

Subject: Windows Defender is Off and can't be turned on 6/12/2007 3:48 AM
PST
By: Undetected In: microsoft.private.security.spyware.general

http://www.microsoft.com/communitie...cc8f&mid=1889ab5c-f476-4371-b7c7-e4b52737cc8f

Hello,

I have a Windows Defender problem on Windows Vista Ultimate x64. It shows in
Security Center that Windows Defender is off, but when I click on the ballon
to fix it (or simply go straight to the Security Center) and click "Turn on"
button the definition update box pops up which sais "Searchin for
definitions..." after some time the box with the error sound shows up with
the message "There are no new definitions available to download for Windows
Defender" and Windows Defender stays off. I use only Vista-Integrated
security tools.

Please, help me slove this problem, as it's very annoying to see those
warnings.

Thanks

Since you are running Vista not XP, navigate to the shortcut for the
Command Prompt from the Start menu and right click the shortcut and select
"run as Administrator." Then, enter the following command:

winmgmt /verifyrepository

Let us know the result displayed.

Regards, Dave

Thank you for your replay, here is what i get after that command:

C:\Windows\system32>winmgmt /verifyrepository
WMI repository is consistent

C:\Windows\system32>
--

Dave M 6/12/2007 9:24 AM PST

I'm really surprised by that result. I expected it to tell you that your
repository is NOT consistent. Can you let us know what the Version numbers of
Defender show for you in the down arrow next to the ? > About Windows
Defender. I'm particularly interested in the Engine and Definition version
numbers as they exist currently.

How about any other security programs running AntiVirus or AntiSpyware or
Firewall... what are they and does security center also gripe about any of
them being turned off?


Also please confirm your system date and time are correct. Having it set
incorrectly can cause this type of behavior.

Can you update the engine and definition version numbers by going to the
malware protection center portal and downloading the Vista 64 bit definition
version manually?

Regards, Dave

Dave M 6/12/2007 9:30 AM PST

I intended to include the location of that portal, which can be found here:

Undetected 6/12/2007 11:00 AM PST

Thank You for advice. What is interesting, after several system reboots
problems with Windows Defender disappeared and everything works fine now. I
hope that these problems won't repeat in the future again.

Dave M 6/12/2007 11:51 AM PST

I wouldn't expect it, but keep those two checks handy if it should
reoccur... the WMI repository check and the system date/time check, both are
easy to fix but initially were hard to identify. They've both been reported a
few times in here as having caused problems with Defender like you
experienced.

Regards, Dave

dirtymoe77 6/17/2007 11:54 AM PST

Mine does this same thing and says inconsistent. How do I fix it?
--


Dave M 6/17/2007 12:52 PM PST

Hi dirtymoe77;

There are three methods, as far as I know... maybe more. I'll post all of
them here for you to take your choice:

1. If your on Vista (which is the only OS to support this command) run the
following from a command prompt as administrator not just using an admin
authority id. It may require multiple attempts to run until successful, so
just try entering it repeatedly, perhaps up to five times until completion:

winmgmt /salvagerepository

If your using Defender on any supported OS (XP or Vista) these techniques
are also claimed to work (courtesy of Steve Boots MVP):

This trick for fixing that issue in XP apparently works in Vista, too. In
Vista you probably need to run elevated. There are two ways of doing the same
thing - the first way is using the GUI and the second way is from the command
line. Your choice. Set a System Restore point first.

Method A

a.. Start>Run>services.msc [enter]
b.. Scroll down to Windows Management Instrumentation and double-click it.
Now click on the "Pause" button. Leave that window open and double-click My
Computer. Navigate to %systemroot%\Windows\System32\wbem (where %systemroot%
is the drive where XP is installed). Delete the Repository folder and *only*
the Repository folder. Now go back to the WMI service window you left open
and restart the service.
c.. This will rebuild the Repository and hopefully straighten out the
incorrect entries for all your duplicates.
d.. In order to see the Windows files, you may need to unhide them:
e.. Make sure you are able to see all hidden files and extensions (View tab
in Folder Options).
a.. Check "Display the contents of system folders".
b.. Check "Show hidden files and folders".
c.. Uncheck "Hide protected operating system files" and click "OK" to the
dialog box.


Method B from MVP Torgeir Bakken (more elegant)

Open a command window (Start/Run --> cmd.exe) and run the following commands:


net stop winmgmt
cd /d %windir%\system32\wbem
ren repository repository.old
(or delete it using the command "rd /s repository" instead of the
ren command)
net start winmgmt

It may take a minute or so to complete while WMI rebuilds the database.

Regards, Dave

Hello Chuck,

Please , don't piggy-back someonelse's thread and at least tell us what
you've already tried so we don't suggest you try something you already have
<w>

1.-Try running sfc /scannow to see if that resolves the issue,
(there is a space between sfc and the /)
also,
2.- consider going to the secuÑity portal.



1.- Run System File Checker.
press enter and let it scan your system, if any files are damaged or missing
they will be replaced using the files on the windows disk

SFC: <http://www.updatexp.com/scannow-sfc.html>


In Vista run it from an elevated command prompt.
Right click command on start and run as administrator.

Every week I have a scheduled scan for Windows Defender and it always comes
back clean. But, now I must admit I am quite concerned that maybe something
is wrong. I do have two compters that are both running Vista and Nortons
2009. I do not have Onecare on either of them. I find it curious that both
compters seemed to have this same problem. I will run Superantispyware after
my Denfender scan is done to see if there is any difference in findings.
Thank you so much for the info and I will post after both scans are done.

I ran Defender and everything came back clean (as usual). I downloaded and
installed Superantispyware and guess what? It found 36 spyware threats.
Unbelievable! I am definetly leaving Defender off and keeping
Superantispyware. Thank you so much for giving me the infor for this
spyware. Between Norton's 2009 and Superantispyware is there any thing else
you feel I should have? I know I am being paranoid, but I have never in all
my years of owning computers did I have any virus', worms, etc. So, I was
very surprised at the last results.

Hi "kls01",

Between Norton's 2009 and Superantispyware is there any thing else
you feel I should have?

No one program never catches & removes everything because there are millions
of possible infections.

Have you doing a weekly or monthly maintenance in your PC,

Part of your regular maintenance plan should be to run in safe mºde. Run
this programs. (MBAM), (SAS) and (WD)

Clear prefetch files

Delete Cookies and Temp Files and included all offline cºntent

Empty your IE cache

I think the story is the same on all the messages in this thread: Windows
Defender is being turned off by the other antimalware product installed--in
most cases Symantec. Current version of McAfee's products do the same
thing.

As to Super Antispyware finding additional threats--definitions differ.
Windows Defender does not worry about cookies--other antispyware products
often do, inflating their statistics.

Yes, every Saturday I do maintainence on both pcs. Disk Clean Up, delete
temp internet files, delete history and delete cookies. I am a very
particular pc user and then creating a 'Safe Point'.
