Here´s how I got rid of the virus where I work, we had about a thousand infected computers.
First make sure, you have your Antivirus program updated and make sure you have a firewall on (we had a problem with the local firewalls on the computers that´s how we got the virus..).
End all ctfcoms.exe processes running. Search for ctfcoms.exe (both hidden and systemfiles, we had the virus in C:\Program Files\Symantec Antivirus and C:\Windows\System32) and delete the files. Then, in regedit, search for ctfcoms.exe and delete everything you can find. That worked fine for us.
I almost forgot, some of the infected computers also got problems with altered Startpages in IE and were not able to change it. You can fix that by editing the Local Computer Policy in User Configuration\Administrative Template\Windows Components\Internet Explorer\Disable changing home page settings.
