dmserver.dll has a virus, how to install clean version.

[Poster Matt]

Hi,

The file on my Win XP Pro SP2 PC called dmserver.dll - located here
c:\Windows\system32\dmserver.dll - has a virus according to my anti-virus
software and confirmed by virusscan.jotti.org where 5 of the AV checkers
showed a positive.

I've no idea how to restore a clean version of dmserver.dll can someone tell
me how please?

Extra important info.: Today I installed a new SATA hard disk and a SATA II
controller card for it. After installation I pointed the XP 'found new
hardware wizard' to the controller card's CD for the drivers, all seemed
fine until I went to Control Panel -> Computer Management -> Storage -> Disk
Management to format the new drive. It was when I tried to access Disk
Management that I first got the 'Virus Threat Detected' which meant I could
not load the Logical Disk Manager Service, which is the file dmserver.dll,
to format the hard disk.

Could this just be coincidence? An anti-virus scan of the controller card's
drivers CD resulted in 'no threats found'.

Please advise, I'm stuck.

Thanks and regards, etc..

That file IS the virus - or part thereof. Why would you want to replace it?

Chances are it is NOT a virus but a trojan. You said you scanned it at Jotti. OK... what
where the detections at Jotti ?

If is is a pure trojan, it can't be cleaned. The DLL itself is malicious. If it is a
trojanized DLL then it may be able to be cleaned.

If is is really infected with a virus then is may be able to be cleaned. The
informationyou obtained at Jotti, but did not post, may provide the needed information.

It seems that 'dmserver.dll' is a component of the "Darkmoon" Trojan Horse
program. I suspect that, rather than repair it, you need to remove it.

You may want to do more research to figure out the best way to proceed.

Well, to be safe try to rename the Dll to something like dmserver.dll.old
and Reboot your machine, does anything complain?

What Jotti scanner showed or reported?
What the properties of the DLL shows and compare on the real Disk Manager
Service file, what you r findings on this comes out?
Bes t if you scanned from other vendors to make sure the file not infected
or the virus itself hooked itself in "%SystemRoot%\".

If you read my post you will see that dmserver.dll handles the Windows
Logical Disk Manager Service and since I need to format a new disk I need a
non-infected version of dmserver.dll.

Thanks for the advise everyone.

And if you read my post there was specific information requested that you left out.

 

[Richard Urban]

That file is **NOT** part of a Vista install.

Again, why would you want to reload this problem file?

 

[Richard Urban]

Sorry. I just reread your original post and see that you are using WinXP.

Is the file in the system 32 folder?
Is the file size 23,552 bytes?
Is the file dated 4/14/2008?

If so, it is likely clean!
