Computer Slow/Locking up - spam found in temporary folder !!

C;\users\owner\appdata\local\microsoft\windows\temporary internet files\content.ie5

and in there was about 250MB of folders all containing the same two pictures, of an album cover that I own (hundreds of them) and a few webpages linking to chrome.

I discovered this anomaly just now when I was running CCleaner, which I had to run in diagnostic mode. Soon as I put it into that everything runs smooth again. Recently it's been getting slower and slower, and it's never been like this since I got it.

So I am just deleting a few things and trying to get to the bottom of it.

Thinking about doing a complete system restore, but that would involve a million updates probably...

Also wondering if I have a virus and looking to run MSE in safe mode at some point. I had about 8 updates pending for a couple of days so maybe that will have fixed the issue.

I had to initially turn the computer off by holding down the power this time, and I've never had to do that before, and when I started it up again in safe mode the problem appeared to be still there, ie. it just seemed to lock up every time I tried to do anything. Managed to restart from there though and have tried a few things. I need to look into this urgently and find out if I have some not not so good malware.

I also looked at internet explorers events log as that is where I discovered the spam folders, and it appears to have been communicating a lot using nvstreamsvc which is something to do with NVidia graphics dirvers, I'm hearing that they have started putting out bloatware.

Maybe I should uninstal MSE and use AVAST instead I heard that MSE is not as good anymore and that everyone uses Avast now?

This thing is running lightning fast in diagnostic mode! must have been something or things running in the back ground that I don't need, and I reckon it's probably something to do with NVidia.

Is it possible to set it to only employ applications that I need, there must be some processes running in the background that I don't need to have most of the time that are slowing things down. I don't understand what they are all though.

I have a lot of stuff installed on this, I need to get rid of some of it I think.

This is what adwcleaner detected, more sweet IM stuff and a few other things
