Hi, my computer was running slow (videos, websites, windows explorer) so I checked the task manager and the CPU usage and physical memory is pretty high. Also there are processes like presentationhost.exe which I have never seen before. Also a bunch of conhost.exe and others so I think I have a problem. Here's a pic of my processes.

The next pic is just scrolled down on the task manager and a few minutes later.

I ran Malwarbytes but it didn't find anything.

I would really appreciate any help I could get. Thanks.

I don't know it says I have to contact Microsoft Customer Services to get the hotfix so maybe I'll try that tomorrow. 

I kinda don't think thats the issue, I think its a type of malware. For instance, Malwarebytes runs automatically on startup but it was closed on its own. 

I think I should try a bunch of other antivirus programs I have first to see if that works. I have Rkill, Combofix, Powerliks.

Ill give those a try first.

Well i did a system restore back to the 15th of August and its seems to have worked. All the extra processes are gone and physical memory is back to a low percentage. Thanks for the feedback tho.
