Just noticed this in your earlier post;
we are letting Spyware Doctor run at start
Spyware Doctor should not be running at start up, which also means it would be running in the background, which can stop any fixes we could try to make.
I am not trying to be "picky or pushy" here but this trying to help clean a machine almost by "remote control"...me giving instructions, you relaying them, him doing...whatever, and then you posting back here really isn't going to work. So far the only thing you have had him run that has been requested by me is the combofix and it evidently was run incorrectly.
You had him download programs that had not been requested, JV16 Power Tools; certainly not one we would normally suggest using at this point, Glary Utilities which is something I am totally unfamiliar with so cannot say I would recommend, I have never even seen it mentioned here by anyone. CCleaner is fine, did he use it?
None of those programs have really anything to do with removing malware, except "maybe" CCleaner since it does remove temp files but other than that I wouldn't use those other two to attempt to remove malware. If they are being used to "optimize" the computer, that is the least of his worries right now.
You say he did an Ewido Scan...where does it say in our sticky to use that? It previously was in there but has been removed in favor of the mba-m program. Since he ran the Ewido scan then where is the log?
You state you found the root of the problem, Purity Scan, how do you know for certain it is the root of the problem?
You say that Ewido found wnscpsv.exe which of course is Purity Scan, but since we have seen no logs from Ewido, we don't know the location, how many instances of it were found, what programs connected to it are on the computer. AND if this is on there, chances are there are other items which need to be removed, but I don't know for sure since I have seen nothing since the original HJT scan and I didn't see PurityScan there. I have absolutely no clue whatsoever of the steps you have taken that didn't work except Spyware Doctor and why put a program on the computer in the first place that requires payment to work when there are good free ones noted in the sticky.
You choose;
Have him run ALL the steps in the sticky, including the Eset Scanner and one other online scanner, allowing both to Clean what they find AND saving the logs, running the mba-m program and also allowing it to clean AND saving the log. THEN a NEW HJT scan and saving the log and DOING NO FIXES WITH IT, or just move on. This is the only way we work here I am sorry.
