System, & Program Issues Are Escalating......

I have been encountering several issues over the last two to three weeks. They started off as what I thought were minor issues at first and have gradually gotten worse. I signed back on when I came back today and got Yahoo instead of MSN (which is my homepage). I have also had at least one program quit working - (Pinnacle Game Profiler) and now I am also getting a Windows program that is not turning on automatically anymore. I get a popup to turn it on by clicking on the selection in the popup box. (This just started today).
I have scanned my system using the COMODO Internet Security Program, Avast, Windows Defender. I have also scanned using Malwarebytes' Anti-Malware and use the scanners in Advanced Systems Care. I have a Hijack Analysis Report from their Security Analyzer.

I have since turned my computer off after hearing a bunch of traffic (it seemed) while I didn't really have any processes (scanners etc) running.

Any and All help that you can give would be greatly appreciated.
Thanks

It sounds like spyware. Have you tried an online scanner such as the one form F-Secure? You can only access the site scanner via Internet Explorer though. Then try running the System File Checker.

I ran the F-Secure scan. It found 13 tracking cookies, but that was it. I am totally stumped and am still not using this computer unless it is to try to clean it up.
I could not find the download for the file checker.

Thanks
I really appreciate your help
