Diskmanager service is it a virus ThatsIT.net.au 09-25-2008

I just noticed a service called diskmanager running on one of my servers.
This is not the logical diskmanager service.
I noticed this service because the description field had a load of garbage
characters in it.
I'm running windows 2000 SBS, I have several other machines running the same
software that do not have this service.
I can not stop it and I cant disable it.

Has anybody heard of it?
How can I delete it?
Should I delete it?

Any ideas?

Thanks in advance

Please provide more detals.

The name of the NT Service
A description if provided
Any dependencies
The fully qualified name and path to the executable/driver and load time switch
paramters
Any other information you can see and provide.

Can you stop the NT Service ?

Can you copy the excutable or driver (*.EXE or *.SYS) file ?

If you can...

Please submit a sample to Virus Total --
http://www.virustotal.com/flash/index_en.html
The submission will then be tested against many different AV vendor's scanners.
That will give you an idea what it is and who recognizes it. In addition Virus
Total will provide the sample to all participating vendors.

You can also submit a suspect, one at a time, via the following email URL...
mailto:scan@virustotal.com?subject=SCAN

When you get the report, please post back the exact results.

OK. As I thought, this isn't good as it looks like a RootKit. I didn't know
for sure so
I asked some peers.

I was given the folowing information...

'svchost -k DiskManager' is used instead of the standard windows service such as
'svchost -k netsvcs' is to cause svchost to "act as a container" for a given
malware
process. What you have may look like what you can see in the following URL...
