System running slow after many AV clean ups

It would be helpful if we new your system specs.
This tutorial by Brink is helpful for filling in your system specs.

System Info - See Your System Specs

As per qmck1999 P.M.

Note: I'm not a security expert.
These are things I would do if it was my computer.

The list of programs you run looking for infection are very good programs.
I do have a question.

In your post you state this.

The AV programs came up with minimal issues

Do you still have logs showing what you are calling minimal issues or do you remember what the issues were?
It could help if we knew what the issues were and how they were handled.

If I had this computer to repair I would remove all those infection scan programs because you are done with them at this time.

Then I would remove Avast using it's online removal instructions.
Then after a fresh boot I would run TFC and then reboot again.

Get TFC from here.

TFC Download

Then I would download and install Malwarebytes Anti Malware and MSE (update both).

Microsoft Security Essentials - Microsoft Windows.

Malwarebytes comes Free, Trial or Premium. Choose one from the Malwarebytes site or Bleeping Computer site.

***What browser are you using??
***Do you have Ccleaner installed??

If you decide to follow my instructions let us know the results and we will go from that point on.

Hi and welcome to SevenForums,
svchost.exe has been a fairly popular cpu eater lately
Mostly because of the windows update system
If you switch to Never check for updates and restart it may return to normal.

You can try option 3 here and wait it out,
Windows Update - Reset

Browser - Mostly Chrome, sometime FF or IE
Do not have Ccleaner.

I am also running Ultimateoutsider's GWX Control Panel to stop WIN 10 updates.

Have followed Layback's protocol above and just finished running MSE, Quick scan, which took 18 hrs. No threats found. Am now running full scan.

So.... Any suggestions?

You could always do a repair install. It will save all your data/programs and just repair anything wrong with Windows. Many cleanings multiply your chances of "cleaning" a wrong thing or two. While all your listed programs are reputable ..... well, you just never know. We have many excellent tutorials here at the forums, written by some very talented people, here's one on how to do a repair install if you haven't before : Repair Install

Because of this in your post #1

In looking at the Services, I see svchost.exe taking about 60%.

I recommend checking your Windows 7 Update settings.
If it is set to Auto Update your svchost could be high at times.

Chrome will also raise svchost because of the way it works.
Check and see how much svchost is being used by Chrome.

Could you post from your computer these two pictures?
Notice that in Services that the box in the lower left Hide Microsoft Services is checked.
