I have the same problem. On the 14th of July I was struck with the Antimalware Doctor virus. I ran Malware removal together with Rkill. It managed to remove Antimalware doctor temporarily. However, when I rebooted the computer Antimalware Doctor reappeared. I removed antimalware keys from the registry which seems to have removed antimalware. I have not been able to reestablish any kind of internet connection and the computer runs extremely slow. I do not know where to go from here, I found out that dfttuyo.exe is also a malware and now I try to remove it. It should be found in the following registry key:
Related to dfttuyo is also the following
I would be happy for any kind of help. Now I am thinking that I need to do a backup of all the programs and files on the infected harddrives and format the disks, install windows again, but I am afraid that the files themselves may be infected.
