100% cpu usage and can not run programs properly

ok so this is my first post and its a gnarly one. I need help with my computer. I am currently on a different one because I can not get anything to run on my other.

So, my computer will start up fine but I can not run any programs properly. I can not open the internet, through internet explorer or firefox. It takes 5 minutes to open anything, files, cmd, my computer, etc. I have noticed that my cpu usage is at 100% all of the time. There are only two processes running that are taking up all of my cpu usage. CCAPP.EXE and PISvc.exe. These processes are averaging 50% each.

I do not know what to do. I can't run any virus scans. I defragmented my c drive and nothing seems to be helping. If there is any more information needed to help with my problem please let me know.

Thank you

 

CCAPP.EXE is the email protection of Norton.

Is it pisvc.exe or pifsvc.exe showing in the task manager. If it is the first then you have a trojan. If it is the second than that too is a Norton feature.

Disable both in the task manager and do the following.

It is pifsvc.exe. I can not disable them in the task manager. Whenever I try it gives me a notice saying I don't have access. I am working on just removing nortoin from my computer but it has been taking 20-30 minutes to open control panel and then another while to open the add/remove program. Is there any way to remove it without going through control panel?

 

You could try Autoruns from Sysinternals (part of Microsoft now).
Uncheck what you don't want to autorun, including services and/or drivers, scheduled jobs, etc. and reboot.
If something resident that you can't kill first, resets what you do, boot up from some Windows on CD (e.g. MiniPE) and repeat the same. Scan your disk for trojans while you're there.
