Hi, I have no reason to believe that I'm infected, as I don't download programs and fire them up, but I just have a feeling that I have an infection.  My CPU will be sitting there and then suddenly fire up to 27, 30, 50 sometimes even 100%.  I lose control of the ability to minimize, maximize, close windows, etc. Sometimes it just locks up for a few seconds.

 

I've run the ESET scanner and it found some programs that I think were false positives, but I quarantined them anyway.  I've run AdwCleaner, Junkware Removal TOol, MalwareBytes, McAffee & Avast Antivirus and TDSS Killer, and they find nothing.  Does my computer just have a problem getting on in years, or do I have an infection?  I'd run Minitoolbox but I don't know how to interpret the log..

 

Many thanks!

Download Process Explorer: http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx
Unzip ProcessExplorer.zip, and double click on procexp.exe to run the program.
NOTE. Windows Vista, 7 and 8 users right click on procexp.exe, click "Run As Administrator".
Click on View > Select Colunms.
In addition to already pre-selected options, make sure, the Command Line is selected, and press OK.
Go File>Save As, and save the report as Procexp.txt.

System Idle Process (CPU NOT used) is listed at 96.30% so I don't see any high CPU usage.

I know, that's the strange part, it comes and goes.  But thank you for looking into this.

Try to run Process Explorer when you see CPU actually spiking.

It looks like perhaps McAfee is eating CPU processes.  Best I can figure.  Thanks for all the help.
