malicious software removal tool

Every month, around the 15th, my profile settings are corrupted and I have to
do a system restore to get them back. The system generated restore point
immediately before this happens is labelled by the system 'Software
Distribution Service 3.0'. On looking into this it seems that at some point I
have accepted an EULA to download and run something called Malicious Software
Reporting Tool, and recently (a few months ago) Microsoft announced that they
would update this program each month (the second Tuesday of the month) and it
would from then on automatically run a system check in the background for
malicious software. I checked on Google and there was one reference to this
potentially corrupting profile settings for users.
This would seem to be the cause of the problem therefore.
The solution on the Microsoft web page was to remove tool from the automatic
updates list, however this item is not listed on my automatic updates (its
not hidden either). I have therefore changed my updates to notify me but not
download or install. When the program popped up a few days ago I did not
therefore download it. Yesterday however I did download a Windows Defender
security update (which I assumed was unrelated), however the system has now
been corrupted again.

Things I have done to try and fix this

1. Tried to remove it using add remove programs - it won't let you.
2. searched for the individual files in the directory to manually delete
them - they seemed to be system files and it wouldn't let me
3. I found a reference to this tool working in conjunction with Windows
Genuine Advantage, so I tried to remove that aswell as in 1 and 2 above - I
did find some files but couldn't delete the main one.
4. did a registry search to try and find these files and deleted a few
entries to at least cause the program to fall over (I hoped), but evidently
that didn't work either.
5. checked my firewall (zone alarm) and blocked the malicious software tool
- no effect (couldn't find Software Distribution Service in ZA so couldn't
block that)
6. tried to find either program in the applications tray to disable it
there (control alt delete) but couldn't see it
7. tried to block it in Windows Defender (in the bit that lists all programs
running) but its not listed
8. contacted Microsoft help on email who were totally useless
9. tried to access their expert user (I assume a blog page) but the system
kept telling me my settings weren't right to access that service. I changed
the settings exactly as they suggested but I still kept getting that message
10. in desperation rang them to enquire about paid support but they told me
they would charge £60 (even if it were a 2 minute job!). I am not prepared
to pay that for what is after all a Microsoft's bug !

The only other thing I can think of to do is to not download any updates for
Windows Defender either - assuming the 2 products are related. However I
won't know the outcome of that for another month since it only happens once a
month.
If it is still causing a problem then I can only assume that the software is
already installed and will run once a month anyway without an update. If
that's the case I need to know how to get into the system files to disable it
- surely there must be a way ??

Any help you can think of to give me would be very much appreciated - I am
certainly trying to fix it myself without asking anyone and have spent many
hours doing so, but I am at a dead end!

For info I am running Windows XP Home, SP3, with AVG and ZA.

Many thanks for your help.

IMO: Drop ZA, use the Windows Firewall. More than enough for most and
doesn't come with the problems ZA users have been plagued with over the last
year or so.

Beyond that - cleanup and update your updating system. After you do this -
perhaps your system will be more stable and you won't have to be so
concerned.

Fix your file/registry permissions...

Ignore the title and follow the sub-section under "Advanced Troubleshooting"
titled, "Method 1: Reset the registry and the file permissions"
http://support.microsoft.com/kb/949377
*will take time
(** Ignore the last step - you should have SP3 installed - if not - you can
do that *later* - it is not necessary to continue with the cleanup.)

Reboot and ...

Search your registry for %fystem and replace the "f" with an "s". May be
three or four matches, may be none. You may even have to take ownership
(even after doing the above) of the keys in order to make the change.

Reboot and ...

Download/install this:
http://support.microsoft.com/kb/290301

After installing, do the following:

Start button --> RUN --> type in:
"%ProgramFiles%\Windows Installer Clean Up\msizap.exe" g!
--> Click OK.
(The quotation marks and percentage signs and spacing should be exact.)

Download, install, run, update and perform a full scan (separately) with the
following two applications (freeware versions are the ones to use for this):

SuperAntiSpyware
http://www.superantispyware.com/

MalwareBytes
http://www.malwarebytes.com/

After performing a full scan with one and then the other and removing
whatever they both find completely, you may uninstall these products,
if you wish.

Download and run the MSRT manually:

Reboot.

Ensure your hardware drivers are up to date (from the hardware
manufacturer's respective web pages.) Never get hardware drivers
for hardware that was not created/sold by Microsoft from Microsoft.
Installing the latest updates may have you rebooting several times,
which is fine - but after you are sure you are done - still...

Reboot.

Download/Install the latest Windows Installer (for your OS):
( Windows XP 32-bit : WindowsXP-KB942288-v3-x86.exe )
http://www.microsoft.com/downloadS/...6F-60B6-4412-95B9-54D056D6F9F4&displaylang=en

Reboot.

and...

Download the latest version of the Windows Update agent from here (x86):
http://go.microsoft.com/fwlink/?LinkID=91237
.... and save it to the root of your C:\ drive. After saving it to the root
of the C:\ drive, do the following:

Close all Internet Explorer windows and other applications.

Start button --> RUN and type in:
%SystemDrive%\windowsupdateagent30-x86.exe /WUFORCE
--> Click OK.

(If asked, select "Run.) --> Click on NEXT --> Select "I agree" and click on
NEXT --> When it finishes installing, click on "Finish"...

Reboot.

Then follow the instructions here:

How do I reset Windows Update components?
http://support.microsoft.com/kb/971058

Reboot.

Log on as an user with administrative rights and open Internet Explorer
and visit http://windowsupdate.microsoft.com/ and select to do a
CUSTOM scan...

Every time you are about to click on something while at these web pages -
first press and hold down the CTRL key while you click on it. You can
release the CTRL key after clicking each time.

Once the scan is done, select just _ONE_ of the high priority updates
(deselect any others) and install it.

Reboot again.

If it did work - try the web page again - selecting no more than 3-5 at a
time. Rebooting as needed.

The Optional Software updates are generally safe - although I recommend
against the "Windows Search" one and any of the "Office Live" ones or
"Windows Live" ones for now. I would completely avoid the
Optional Hardware updates. Also - I do not see any urgent need to install
Internet Explorer 8 at this time.

Seriously - do all that. This is like antibiotics - don't skip a single
step, don't quit because you think things will be okay now - go through
until the end, until you have done everything given in the order given. If
you have a problem with a step come ask and let someone here get you
through that step. If you don't understand how to do a step, come back and
ask here about that step and let someone walk you through it.

In any case - no matter what - when you are done doing whatever you decide
to do - please - come back here and let everyone know what you did and
how things turned out.

The relationship between the two is almost non-existent. Furthermore,
indiscriminate file removals may render your system even further

6. tried to find either program in the applications tray to disable it

You brought up "Task Manager", and Task Manager displays running
applications. While running, Windows Defender is a "Process".

Keeping your system from being updated is "Cutting off your nose to
spite your face".
However I won't know the outcome of that for another month since it only happens once a
month.
If it is still causing a problem then I can only assume that the software is
already installed and will run once a month anyway without an update.

This is a reasonable assumption.

Surely there must be a *better* way!

Exactly which AVG product are you using? Be very precise.
Many thanks for your help.

When did this original trouble first start? Can you relate any other
system changes at that time with this trouble?

Do you have any other antimalware applications?
 
MS has been downloading this tool around here for quite some time (at least
two years). It is part of the monthly update package. That restore point
that you mentioned is the one which the monthly update package makes before
starting the update.

As for whether MRT corrupts or does not corrupt profiles is something that I
do not know. I do know that it never has corrupted any profiles on my
computers.

Before doing anything else, you should insure that there is no malware on
your system.

Thanks ever so much for this very comprehensive reply. I am however somewhat
concencered by it, to say the least !
this seems to be a very drastic set of steps to take, which, if i understand
you correctly will disable a lot of stuff on my computer (even if it is
subsequently reenabled). For example
why would uninstall my browser (IE8)
why would i download MSRT maually when that is the thing i am trying to get
rid of
why defrag
why check drivers

all i am trying to do is remove the MSRT - everything else works fine.
I do have superantispyware and run it regularly, doesn't find anything
though (apart from the odd cookie)

i don't know how to save to the root of the C drive.....

the other post says i can simply delete the .exe file - i will try that first.
thanks again.

its the free version

system changes at that time with this trouble?
it started an few months ago and happens once a month around 15th. no other
changes that i am aware of.
Do you have any other antimalware applications?

yes, spybot, superantispyware, defender, ad-aware anniversary edition,
spyware doctor (though i have to disable this one from real time because it
takes up too much resources). all are free versions and i run them all
monthly. don't generally find anything significant on any of them.

thanks for your help.

No. However, I sincerely believe this is a move in the wrong
direction. If your goal is to temporarily delete MRT.exe to see what
happens, OK. I would reinstall it afterward though.

Excellent.

its the free version

I'm afraid that's not very precise of you! You are not giving away
security secrets about yourself. Precisely what version is it?
it started an few months ago and happens once a month around 15th. no other
changes that i am aware of.

Had you recently installed any applications or utilities?
yes, spybot, superantispyware, defender, ad-aware anniversary edition,
spyware doctor (though i have to disable this one from real time because it
takes up too much resources). all are free versions and i run them all

You may wish to add MBAM to your lineup:

thanks for your help.

Shenan has passed you a very good method for doing a comprehensive
clean-up of your system.

All though we read many posts that extol the virtues of IE8, we also
see many anecdotal stories of falling back to IE7 because of slowness
or obscure troubles.

Downloading MSRT again assures you that your copy is corruption free.
 
lopar

Do you have Zone Alarm installed? It is the cause of this issue. Uninstall ZA before
downloading the Malicious Software and any Defender Updates. Best to remove ZA and
use the built in Windows Firewall which does a better job anyway
 
OK, i have tried to find the mrt.exe file using search inc hidden files and
system files. there was nothing except an ie log text file.
(by the way, and please don't think i am being funny since this is the first
time i have ever posted anything anywhere, you say the file might be located
in /is/ - is that a file location, or a piece of jargon or soemthing else - i
genuinely don't know what that means (or am i being too literal and you just
mean is !))

i am beginning to think its not mrt after all but somehting else. however
what could possibly delete my settings every 15th of the month ?

sorry about imprecision on AVG - its 8.5.409 - is that what you wanted ?

i can't say for sure about having installed any applications or utilities -
i don't recall doing so. would a check on add remove programs by date be
sufficient to tell me ?

On my system, the file MRT.exe is located in c:\windows\system32. It is not
a hidden, system file.
As Windows is not case sensitive, mrt.exe and MRT.exe are just two ways to
spell the name of the malicious software removal tool.

Unfortunately the devil is in the details...

If the standard issued Microsoft Malicious Software Removal Tool is
installed in its usual location, it should be at:

C:\WINDOWS\system32\MRT.exe and has a 24,111 KB file size

I tied to make everything case perfect as it would be in your system.

I checked on one of my systems and MRT.exe can definitely be deleted.
i am beginning to think its not MRT after all but something else. however
what could possibly delete my settings every 15th of the month ?

I never did. You could set MRT to scan on some other date to
eliminate this theory.
sorry about imprecision on AVG - its 8.5.409 - is that what you wanted ?

That's the latest free version of AVG and that's very good.
i can't say for sure about having installed any applications or utilities -
i don't recall doing so. would a check on add remove programs by date be

Maybe not. I was hoping your memory might help here.
 
Thansk very much again. there is nothing in explorer by that name, in
windows there is a SYSTEM32 but its in capiltals, not lower case as yours was
(does that matter?) but there are no mrt entries at all in the system32 area
when i expand it.
if i can't locate mrt presumably i can't set it to scan on a defferent date?
someone else has said the probelm is cuased by zone alarm. i can't find any
refernces on google to this - do you think that might be correct ?
 
lopar said:
Thanks very much again. there is nothing in explorer by that name, in

That is suspicious.

Have you seen the corruption this month?
 
Yes i do. can i ask how you know this to be the case - i have checked around
some sites but can't find refernces to za casuing a loss of settings when
getting a security update. is there a link you could give me ?
is it just certain versions of za ? i have 8.0.298 is there a fix in za -
i am reluctant to get rid of it.
or alternatively would it be enough to shut za down whilst installing
updates (and use windows firewall temporarily) then start it up again
afterwards ?
thanks for your help
 
yes i saw the corruption on 15 this month.
i know about chkdsk and can run that if you think i shoudl but not heard of
the sfc one - can you tell me how to do that ?
 
Latest thoughts/activity: since there is no mrt file it can't be running
automatically, therefore the problem is related to a download. ? link to za
? have manually downloaded the defender updates now from this link
https://www.microsoft.com/security/portal/Definitions/HowToWD.aspx?wa=wsignin1.0
and no effect, therefore its something to do with automatic downloads.
(incidentally, i have to use this link to get updates to defender since the
update tool in defender doesn't work - it tells me there are no updates
available even when there is an icon in the sys tray telling me there are
updates. this might therefore be relevant).
therefore i won't donwload next automatic update and see if problem recurs
on 15/10. if it does there is something running on the mahine. if it
doesn't then theory confirmed, get the specific KB download manually, recheck
for problem, if it occurs do system restore to before the download then get
that specific KB update again but with disabled za (disable rather than
uninstall) and see if that works.
are you good with this logic ?

answers to your questions
1. have now run chkdsk and no probs
2. have checked scheduled tasks and nothing with that date in
3. will get sfc tomorrow (don't know where you are writing from but its 4.30
am in uk and i'm tired !

thanks for your patience......

My gut feeling says the trouble is elsewhere but where I don't know
yet. You won't harm your system from what I read and you'll learn
something.

Drat!

I understand.

In the US, I'm a third of the world away from you, but I'm up anyway.
Obey the call of Morpheus.
thanks for your patience......

You are very welcome.

I was hoping you could find time to follow Shenan Stanley's suggestions.

Honestly, after that, the best move may be a "Flatten & Rebuild" but
we can still check a few more things before then.
 
i have had another thought, which i hope is not a source of great irritation
to you because i have only just thought if it.
the corruption only occurs on my profile - there are 4 profiles on the
system, 3 of which have admin rights inc mine (though no one else in the
house does any system stuff or downloads). this realisation made me think
about what the differences are between the profiles and the only difference
is that mine has a non standard MS product on it - a screensaver
http://www.download3000.com/download_45524.html
it is available to all users but only activated on mine. plus i installed
it in May and have been encountering this problem for about 4 or 5 months (so
about right).
is it possible then that there is some weird interaction going on between
the s/saver and the defender /mrt updates (which are the only ones seeming to
cause the problem)? if so is it possible to keep the s/saver (which is
really rather nice) and also fix the problem do you think ?

i have also now run malwarebytes and it found a few things inc a trojan.
didn't look significant, but i wouldn't know....

on Stanley's sugestions, very comprehensive and welcome, however a last
reort for me, partly because it looks like they would take 2 or 3 days to
work thru and partly because they seem to involve uninstalling a lot of
products and updates, and for a relatively inexperienced user like me (i am
