What kind of malware is this?

So one of our computers here got nailed with some malware.

Spybot didn't detect anything. and was banned from updating
Malwarebytes didn't detect anything. and was banned from updating
Superantispyware wouldnt run

I deleted the parts that loaded via the registry,killed the running process, updated and ran all three programs again.

Superantispyware removed 11 components (one of which was funweb)


I thought that it was gone.

This morning our corporate install of Kasperksy Antivirus killed this:
c:\documents and settings\alan\local settings\application data\ebnveh\tkhqsftav.exe

I deleted the directory.


Behavior:

Originally:

Showed fake virus warnings
Gave false warning on Windows Security settings
Porn pop-ups
Taskbar infected pop-up
Blocked updates to anti-malware programs
Installed Proxy into Internet explorer 8 127.0.0.0 : 5000

Hyjack this shows nothing unusual and I mean not a thing.
Everything in the Hyjackthis log version 2.0002 has been verified.
Nothing is listed in MSconfig
Nothing unusual is loading from the (Run or Run once) listings in the Registry

I 'm down to checking for a rootkit at this point.

Short of setting the machine to create a bootlog and dissecting it I'm running short on ideas.

Somehow this bugger is still reloading the proxy and rebuilding the directory on boot.

Any ideas?

Thanks,

Mackintire

Update 2/24/2010

The proxy reloading may have been a fluke leftover from the last reboot. The rootkit scan came clean and we rebooted with no signs of infection. It'll be a few days before I call it verified clean.

This forum was set up specifically to help home users, we do not work on business machines.

Computers used in a business environment often have policies and other modifications made to them. It is impossible for us to differentiate these from ones that have been made by an infection, so in removing what we think is an infection, we may compromise the business set up of your computer.

The scans we run often reveal information that most businesses would not want exposed in an open forum, and there are other legal constraints and ramifications involved with business machines that we are not equipped or trained to deal with.

I'm sorry but we can't help you.

As this computer is likely to contain sensitive business data, it is in the best interest of the company to reformat and reimage the drive.
