I am getting a message from McAfee that a Trojan has been detected that cannot be quarantined.

Vundo.gen.ab
Location: C:\windows\system32\diyadodi.dll

I found a guide on Bleeping Computer on removing Vundo, but am having trouble.

My hard drive keeps filling up. As soon as I delete something, I get a message stating that I am out of disk space. I also cannot even get IE to open up any more. I was finally able to copy over rkill.com from another computer and am trying to run it. The first couple times I ran it, an error mesage came up stating that an unknown error was found and the program would be terminated. I started rkill a third time at it is still running, so maybe it will get through this time.

My next step is to run MBAM, but I don't know how I will ever get it copied over with my hard drive space issue. Can I run it from an external drive, or does it have to be on the computer's desktop?

Thanks for your help.

Hi,
since you have another machine to use. Disconnect the infected machine from the network. At the other machine you will need to download a couple of files.
ATF cleaner from http://www.atribune.org/index.php?option=c...5&Itemid=25
Malwarebytes from http://malwarebytes.org/

Copy these files to disc (CD preferably). Take them to the infected machine and do the following:
Run Rkill
Run ATF Cleaner by double-clicking
Select All and click "empty selected"

When finished install Malwarebytes and update it. Run a quick scan. Remove any infections found and post the results in your next reply. Reboot the PC when instructed.

Good that you got MBAM running! Now do the following.
