Interpret "RATTV3" results

[fix-it-upper]

I'm trying to figure out what is causing my grandmothers computer to have the cpu at idle running 90% all the time. Can anyone here read RATT results and interpret them for me? I don't understand how to read them. What is causing my cpu to be going so fast as no process I can find accounts for it in task manager. I can send it to anyone's emaill address but it is too long to post here

Sincerely,

ben

Try this (has other links)

A google using RATTv3 as the search term brings up more links.

First thought would be some sort of malware - have you done a scan on the system? Is there any AV protection installed?

Yes, i did virus/malware scans that all were negative. I used Norton, spybot and adaware. I'm trying a fresh install of xp now to see if it fixes the problem, if not this computer is probably headed to the dump.

The links were good, but still over my head. I read them but I don't think I should even try it when a fresh install would take me less time and I only have till tomorrow evening to get this fixed, then I leave back home from visiting.
