Please post the make/model of your computer along with the system specs.

To find which process is hogging the CPU, press Ctrl-Alt-Del > Start Task Manager > click the Processes tab > check the box for "Show processes for all users" > then click on the CPU column heading to arrange the processes in order of CPU usage. Which process comes to the top?

NOTE: System Idle Process does not hog the CPU

No virus checker finds anything. These three freebies use a different approach - run them in the order given:

AdwCleaner:
http://www.bleepingcomputer.com/dow...
(blue Download button near top - not anything else on the page).
Download and "Save" the file somewhere. Go to the saved file then double click it to run the program. Use the "Scan" button, followed by the "Cleaning" button.

Junkware Removal Tool (JRT)
http://www.bleepingcomputer.com/dow...
(blue Download button near top - not anything else on the page).
Download and "Save" the file somewhere. Go to the saved file then double click it to run JRT. It might appear to have stopped at times or flash the screen but sit tight until it has finished.

MalwareBytes:
http://filehippo.com/download_malwa...
(green Download button top right - not anything else on the page)
Install and Run the program but before doing its Scan go to "Settings > Detection and Protection" and put a checkmark in "Scan for rootkits". Quarantine anything it finds.

Please copy/paste the logs on here. Even if the symptoms go away further checks will be necessary to ensure your computer is properly clean.

Always pop back and let us know the outcome - thanks

You've got some resource-hogging norton product monitoring your computer and you wonder about high cpu usage? Temporarily disable all your norton stuff and then check your cpu usage.

I agree with Dave, 55% CPU usage is about right for that hog unless it is a very fast system. If it is proven that it is Norton itself, ask us about better options for your protection.

You have to be a little bit crazy to keep you from going insane.

On Malwarebytes, select 'End Free Trial' to revert to Free Version. You only got the Trial Version of the Pro Version because you did not uncheck the trial check box when you installed it.
Norton is not cheap. Norton is not especially good. Norton uses system resources wastefully. On a netbook or other system that is not especially fast or powerful, that means a lot. A lot of people here use Avast Free Version and find it better than Norton by a long shot. I have used it and it is significantly better. I personally use Webroot Secure Anywhere (just the antivirus version only, not the suite) and I find it much better and especially does not have any of those pop up warnings when they are not needed. If it blocks a web page and suggests that I not proceed, then I do not. Their warnings are rare but actually important, everything else is taken care of in the background. My CPU usage by Webroot is currently Zero.

"system idle pr user name SYSTEM CPU 98"
That particular one often catches folk out. It means 98% of the time it is doing nothing (idle). A high figure for that is just fine.

MalwareBytes should still continue in it's basic form after the trial runs out, which is quite good enough.

Always pop back and let us know the outcome - thanks
