Infected... please help?

Hey guys, unfortunately I have somehow been infected by several high level security threats. I ran Avast yesterday and it said it found several viruses.

After trying to remove them, Avast scheduled a boot time scan for me, which I did. Here are the results:

As you can see more infected files were detected, but Avast was able to successfully move them all to the chest. However, after, when windows booted back up again, I was unable to open and run most programs. I assume this is because Avast removed important windows files to the chest, thus causing windows 7 problems like not being able to run most programs.
So, I did a system restore and everything went back to normal. I then ran a scan again with the following results.

So, now I’m scared to take any further action because since these might be important windows files, removing them can cause problems, right? Which is what happened to me in my first attempt… I think.
I need some help removing these viruses guys, how do you remove something that’s in these files? I ran both Malwarebytes and Ad-Aware, neither of them detected anything. What should I do now?
I really appreciate any help.

what type of scan did you run…quick / full / custom ?
have you changed any of the default scan settings ?

Full scan, I ran it about 3 times again to confirm the results, and they were the same every time.

And no, I have not made any changes to the default scan settings.
