What I meant and was going to suggest is that to clean that drive properly is to retrieve any data such as pics Docs and any programs you really need (say paid for ones) and then do a complete reinstall.
This is a good tutorial to follow for the install as it has the latest ISO and will cut down on the updates Clean Reinstall - Factory OEM Windows 7 this means though you have to format and get that drive ready as new to do this.
Just make sure you pick only the version you have others get greedy and it ends in grief - see pic
and this SSD Alignment

I think in the long run this may be your best option and just in case you do do this then use this to make an image for future problems if they arise - so much easier than plodding through installing everything you like

Imaging with free Macrium I set my machines to do this at weekly intervals - saves so much hassle

Well, what I mean, is that on a laptop, I know, at least, I can actually do a factory reset of the laptop. It reverts back to an out-of-the-box condition, formatting all files, and keeping windows. The infected files, I would assume, could be cleaned and put back on the reset computer.

Well you are right 2stone but it does load all the crapware and doing it the way I laid out there is none of that and believe me it saves so much on boot time and loading the essential programs.

I have done this a few times and even used an OEM and the effect on the machines performance is just what you need.
