Unable to perform system restore.
After reviews I decided to run TDSSKiller, which removed the Bootkit.TDSS.  Ran Hitman Pro...gone...it found another virus and would activate.  I will continue to do my thing...will let you know what else I find.

I want to run sfc /scannow but have read -  You may need your Windows XP CD so have it ready.
If you have Service Pack 2 (SP2) or SP3 installed, you will need the SP2 or SP3 version of the versioof the CD. This can be done with a borrowed CD, if you don't have one. I have a XP disk and both SP on disk...will this cause a problem should I need the CD?

Also Windows update is not working...researching the error code now.  Error 0x80070424

Hi Mags,

The situation with XP Media Centre Edition - is it 2005 version?
I have this running still on an old PC, and face the same issue on most occasions where OS fix-up is necessary.

The Media Centre Edition 2005 operationg system comes on two disks. The first disk contains the operating system, the second contains the Media Centre app and its gubbins.

So when it asks for Windows XP SP3 disk, you want to use disk 1. HOWEVER, if that disk doesn't include SP3 then sfc may reject it.

Is that what's happening - you tried disk 1 and got nowhere?

Thanks,
Avatar of Mags

ASKER

yes...it rejected every disk I tried...no XP disk has SP3 that I know of...is there a work around??

Can anyone figure out the combofix files (see above)...still having issues.

The reason you where having problems running combofix in regular mode is because of Microsoft Security Essentials.

Hi MagsMcKinley14,

It sounds like a bit of a 'mare :)

If you are still getting nowhere with the main problem of removing the malware despite the advice of those who have already posted, then try this:

http://www.sophos.com/products/free-tools/sophos-anti-rootkit.html

I have had some success with this - the other specific anti-TDSS tools are very useful, but (apart from ComboFix) are unlikely to handle a "blended" threat well, which might be what you're seeing here.

To my knowledge the only way to get past this issue with sfc would be to use something like Microsoft Deployment Tooklit 2010 to "slipstream" the Service Pack needed. However it cannot be done with Windows MCE Edition 2005...  at all, according to Mcirosoft. :(

There are so many inter-dependencies in MCE 2005 that it is in practice an unreliable OS IMHO - I spent more time reinstalling the system running it than I did using it, sadly,  mostly due to MS updates for .Net and MSXML parsers whose dependencies were either not set correctly, or whose initial revision was broken and subsequently borked the entire system during install (the Media Centre app is very dependent on .Net).

Your best bet - and it's never entirely satisfactory - is to clean up this malware and confirm it is gone, then perform a "reinstall" (over the top) of the existing Windows install. Thatn will retain user accounts and settings (including Media Center channel listings etc.) but you will lose all patches to the OS, and need to re-do them (I suggest directly installing SP3 at this stage if you go this route).

If I can help further please post back.

Hi MagsMacKinley14,

The advice is to run Sophos Anti-Rootkit in normal mode - it will find more if all Windows services are up and running, including those "boot-start" kernel-mode drivers which are responsible for "sentinel" operations on a rootkit.

Look forward to hearing how it goes...

Thanks again guys!!
Hi Mags,

The output from Sophos Anti-Rootkit looks OK to me - the listing of files you see is its "err towards paranoia" approach to detection. Most if this looks like SAR doesn't like those files' hidden status. However we'd need to manually checksum each one individually against a known good, current version to be certain of its integrity.

I'd get rid of the setup_av_free.exe in the "_Downloads-Save" folder - whilst it's possibly AVAST! it's location in a non-standad folder is what makes me suspicious.
Also the multiple copies of the MS Message Queuing binary all pulling the same trigger - mqtgsvc.exe - is suspicious.

I'm gently urging you towards a rebuild Mags, as it's going to be difficult to verify the health of this machien to reasonable satisfaction. Assuming you want to continue though, and wish to verify each of these files, try this:

http://www.sunbeltsecurity.com/sandbox/

The above link is to SunBelt Labs Sofwtare's CWSandbox, which does malware profiling. You submit a sample of e.g. mqtgsvc.exe to the site, and it will send you a report of the processes, threads and registry entries created by the malware (if it is malware). You can then check for those processes/registry keys to see if the file is part of your infection.

Recommendation: when you come to use Dial-A-Fix, do your backup of Documents and Settings using another operating system if at all possible. This limits the chance of your backup media getting infected if the TDSS malware variant present includes worm-like behaviour.

Keep asking if you think I can still help!

Thanks Hapexamendios: for your advice.  I ran Sophos on a couple of files that had Malware written all over them after researching them, the 2 WildTangents and got rid of the ones in "My Documents", manually deleted the Advast.exe then backed up her files to an external drive after I scanned it.  Is there a way to test it again to verify no virus or should I pull the drive and make another backup?

Also she has the primary drive mirrored but I would assume it would bring over the virus as well.  I see no real advantage to mirroring a drive if it continues to update and you get a virus...would you agree?

She has a backup on an external drive that I will check for viruses now.

I am starting to agree with you about a rebuild or she may want to upgrade her computer as it is getting old.

Let me know about the backup I did and then I'll run Dial-A-Fix.

Do you know anything about Norton Power Easer?
I confess not to knowing much abotu Norton Power Eraser - however I'm very wary of utilities that automate the deletion of things, especially registry entries (I believe it does these things?)

You're right about the RAID mirroring - undoubtedly a great facility, but adds an extra layer of complexity where a virus that utilies raw commands to access disks is involved...!

I'm thinking that scanning her backup (and any USB flash/pen drives she might have used with this system prior to your support work starting) is a must - do this either using a completely separate computer with up-to-date AV -OR- boot her computer into another non-Windows OS (which can't be infected by Win32 PE code). Once yo've verified those items are clean, you could optionally retain one of the disks from the mirror set (just for ultra-caution against some obscure piece of data you haven't yet backed up) and then you're in place to start again.

You mentioned maybe upgrading the PC - I'd say if nothing else, please oh please ensure new HDDs are used! If you ever need to access the old disk with the mirror on it, again slave it to anotehr machine or use another OS when accessing it.

How's this sounding so far Mags - have I missed any of the questions you asked?
I would suggest using raid 1 (Mirroring) because it provide redundancy. If one drive goes bad just pop out the bad drive and Install new one and let the raid controller rebuild the array.
meko72:

which would include any malware that was within the logical volumes in the mirror set... You see the difficulty? I wasn't "dissing" RAID 1 or 1+0 - it's brilliant - but not helpful here as it adds yet another thing to scan, and you can't easily slave said disk to another machine for scanning (though I know it's not impossible, just an extra hassle).

@meko72:

Let's not spoil a good effort by arguing; I accept what you say at face value, but I think you might be underestimating the complexity of modern rootkits. They use kernel-mode, often undocumented API calls and other techniques to directly create a little portion of disk space especially for themselves on the physical disk. This is achieved by talking directly to the disk controller, lopping a tiny amount (1MB or less) off the free space on a disk.

It wouldn't take much to do this on "x" disks, where "x" is the number of disks, and adjust the array's byte count of each drive so that the volume(s) are never seen. Do you see what I mean? In effect the data involved is therefore not part of the mirroring. These tiny 1MB partitions are how this stuff survives a reboot - and when the compuiter comes up, the code removes the volume and all files on disks, heading into memory reserved for kernel-mode, and stealthing itself by constantly copying itself to new memory regions on a pseudo-random basis.

That's my understanding anyway, and makes me less likely to offer advice that it should be OK. And of course none of what I've said here applies to stuff that IS visible on your disks and in your partitions; that would of course work exactly as you have described it.

Peace... :)

  In the past I have had to Unistall all of the .Net Framework  and reboot to get a virus off of a machine.
I would go ahead and run SuperAnti Spyware and Malwarebytes..

There is another utillity called Rkill. When you run it it will find any Backdoors,Malware, Trojens and Rookits that might be running and kill them.
I use this application after I have cleaned a machine just to make sure.  The link is Below.

@Mags

Removing .Net from an MCE 2005 Edition computer will sadly trash it completely. If others can say different I bow to their expertise and wait for their advice eagerly.

My MCE 2k5 machine is still offline after two years because I got tired of issues with .Net framework patches!

I'm curious as to why uninstalling it might be needed, though. I guess some of these things are .Net based naturally?

Not good in this specific case though :(

No...things are running well.  I got a blue screen error related to a driver issue...with HPProductAssistant needing a disk????? I uninstalled and reinstalled the new printer software they just recently added.

They needed the computer back so I will run a couple more scans remotely.  I should have things completed by tomorrow…then will close the event.

They are still considering a clean reinstall or a new computer as a safety precaution.
Sounds good - accept what is a low risk in the short term, and maybe, for similar features, go up to Win 7?

wait to hear what comes, then.

Cheers,
If the Machines is running fine, Then I wouldnt unistall / reinstall net framework if you dont have to.
