Can't Remove Trojan / Adware

Have you just installed Service Pack 2 onto this PC? If so, was it before or after the infection?

I installed a couple of months ago…….the infections happened afterwards.

The problem is that I can't see anything that I can identify as malware in any of the logs that i've looked at. While this doesn't rule out a malicious cause at the root of your problem, there is a chance that this isn't a malware issue. Did the installation of SP2 coincide with the speed issues on your PC, and has you anti-virus stopped detecting anything malicious when you scan?

No the speed was fine after reinstalling and up until I got the adware infection………..when I scan with Windows Defender or Spybot, no infections are detected………..when I scan with Spyware Doctor, it tells me that I have 7 infections of Adware.WinFixer….5 Registry Value….2 Registry Key…….I don't want to purchase the Spyware Doctor to remove the threats as I believe that I received this infection to begin with from someone/something that gave me the virus for the sole purpose of buying Spware Doctor (this is what I was directed to when clicking on the pop ups to clean my system)…….and I don't think it will do anything to benefit the situation once I have paid. ….any thoughts?……….Thank you again for all of your assistance.

Can you list EXACTLY what is being detected - the key names rather than the general infection names. These keys are probably leftovers from the original infection and pose no risk, but it's good housekeeping to remove them. It is important to get these detections right as incorrectly editing the registry can do terrible things to a PC - even render it unbootable.
As to Spyware Doctor being at the root of your troubles, i'd be a little surprised - as far as i'm aware the company is legit: http://www.pctools.com/spyware-doctor/ I'm assuming that this is the product you are referring to?

Hi Noviciate - Please see the below info and let me know if it is helpful information?….I also included the links to the scan reports that you will hopefully be able to view…..Thank you again for all of your time and assistance!

I'm afraid that the information you've posted is of very limited use.

when I scan with Spyware Doctor, it tells me that I have 7 infections of Adware.WinFixer….5 Registry Value….2 Registry Key…….

You said that there were 7 registry items detected - can you tell me what they are - I assume that Spyware Doctor lists them by key name and value rather than by names such as not-a-virus:Downloader.Win32.Agent.d.
As an example: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run is a registry key.
