Hello,

I'm new to this forum and hope somebody will help me.
We have on our HP server for the last 2 weeks a lot of BSOD.
Never occured before. (We run terminal server applications on this server.)

No hardware nor software changes made prior to these problems.

The dumpfiles are all the same and :

What is this vdo...sys

I have read somewhere this is an infection.

On the other hand I have found in the windows observer one error linked to the driver/ATI2MPAD.

What can be the problem ?
Wa have changed our ram, put a new motheboard, downladed servicepack 2.

The problems subsits?

Anyone ?

Thnaks,

But

Vdo_1040-78f4.sys is an infection. You can find the same problem HERE. They didn't say which program found it (post #10).

Thanks for the info.
The link is not much help since it does not explain how to remove the infection.
Our AVG Anti spyware can not find anything.
Sophor antiroot kit did find some hidden files inregistrey keys : vdo* and vdo_g.ini.
My question is if I may remove these files :

c:\windows\system32\vdo_g.ini
c:\windows\system32\vdo_1040-78f4.sys

Sophomor does not recognise these and therefor does not recommend to delete.
Or what other things should I precisely do ?

Thanks for the help !

I think they are safe to delete. As spyware isn't my thing, you can always ask in the security forum. I also found THIS, which pretty much confirms it's a rootkit.

Thanks for the reply.
I have deleted them, rebooted the computer without problem.
I will post the outcome later.
Thanks,
