This file has the same date/time stamp as the PP11 file left behind by a Trojan which I downloaded over the weekend as a result of those websites being hacked. I was able to get rid of the Trojan and delete PP11 - but my computer won't let me delete DDNS. I know this is the problem because I cannot access any websites - which is a DNS error.

The ddnsfilter runs as a service, under the control of svchost.exe
To find it, you can open a command prompt, and type tasklist /svc
Now find the svchost which is running ddnsfilter, take a note of the process id, and use task manager to end this process. You can now delete the file from c:\program files\ddnsfilter (program files may have a localised name, for instance mine was located in c:\programmer\ddnsfilter as I'm from Denmark.)
Good luck ! :-)

Jean's advice worked great! This was the last little remnant of the latest version of the Koobface worm, which I'm currently cleaning off of a friend's machine.

I recommend checking out the list of files at http://www.exterminate-it.com/malpedia/remove-koobface
It was very informative on what files and registry keys to remove.

Seems like this should work, but everytime I open command prompt and type in tasklist/svc I get a message that tasklist is not a recognizable command. What do I do?

I'm running xp home edition, which does not come readily programmed with tasklist. I installed a tasklist program from computerhope.com and everything worked great. Tasklist was then recognized. The info also helped me figure out which .dll was running for each svchost, etc. Good luck. Nasty little bug. Here's the link:

Jean, Thanks for the advice, it put me on the right track. I still had trouble deleting the file, but after rebooting into safe mode I was able to delete ddnsfilter. After that I was able to use Kaspersky Internet Security free 30-day trial to completely remove all remnants of the malicious code.

Chad, it looks like you need to add a space after the command "tasklist"...it should look like this: tasklist /svc <Enter>

Thanks!
Brian

I was able to defeat the monsters! I threatened my system with total recovery (which wasn't needed), and then zapped it with McAfee. It seems a ddnsfilter.dll file was hidden in my windows/system32 folder.

Another option is to go with a program called Remove-on-reboot. Simply right click on the file (typically in programfiles/ddnsfilter as Jean said) and use the "send to" option to send it to "removeonreboot." Restart and it's gone. Then virus scan and eliminate all the pieces. Good luck all.

tried - remove on reboot and it did not work.
My anti-virus has found it and cannot delete it. not sure how to get rid of this one. Is there any other options to try?

Ditto on the ddnsfilter.dll issue- I didn't go so far as to grab the program, but instead sniped svchosts until Windows let me delete the file.

Lilly- perhaps try deleting files and registry entries by hand? Joe's post above has a good link for a list of them; it was helpful for me.
