What has happen to my system? runnning Vista on a HP AMD 64X2 dual core processoer SP2. 3G of memory. Have IE7 installed and when I open up a web page it uses 50% of the CPU (other 50% is idle for 2nd processer). The CPU usage goes down when the entire site has been loaded (does not matter which site I go to). I can increase the cpu usage up to 30% by just moving the scroll on my mouse up and down (do it real fast). I run Norton all the time and have used other free scans and none of them show any infections. iexplorer is only running once in the task manager and does not show up on start up (only when I launch it). I start in safe mode with no add-ons and the CPU is also High; have run defag, empty recycle bin, clean disk and CPU is still high. Ran hijack thsi and attached log file below.
