Dealster / Deailsterr

I have been fighting a browser add-on named Dealster that has done a number of bad things to me, including signing me up for the IC*freeShipping.com scam. I finally tracked it down to \ProgramData\Mozilla\2.x64.dll and killed it by using Admin Command Prompt to remove the entire \Mozilla directory but it is back, changing its name to deailsterr. It is active but inaccessible to IE 12, Firefox Aurora, and Google Torch.

MS Security Essentials, MalwareBytes AntiMalware, and Wise Care 360 are all unable to find it. IObit can not run as Win 8.1 (64 bit) has declared it to be malware and disabled it.

Any suggestions (especially a cure) would be appreciated.

 

I did all that before my post but it did not help. Dealster & Dealisterr are invisible to ordinary anti-malware. There is a lot of information available on Dealster (http://www.411-spyware.com/file-2-x64-dll for example) but nothing on Dealisterr. The latter lacks some of Dealster's ability to do mischief but I want it gone as I suspect that it is still able to cause trouble.
