You should follow Essexboy instructions, there are probably more Adware on your system.
there are the link :
https://www.virustotal.com/ar/file/4733d12194f3cac2435962c94265d7a8424cad228a8f6bde3cd0817c7eb29039/analysis/1399386961/
there are the files attached…
upoloading OTL diagnostic logs to virustotal does not tell us much… they are not the infected ones. ;D
it is the dgen.exe file you need to upload and test. 
File C:\Program Files\PCDApp\dgen.exe is infected by Win32:Miner-B [b][PUP],[/b] Deletedbut i guess that is to late since you have deleted it PUP = not virus / Possible Unwanted Program ..... usually crap that comes bundled with freware downloads....
On completion of this let me know of any remaining problems
