Hi,
My CPU usage is erraticlly high with iexplore and rundll32.exe high. I have installed many different tools (prob too many) and don't see anything specific and I don't know what to do to fix this. I tried to do this myself (like get rid of (Canon) BJMYPRT.exe and couldn't restore an old system restore point after this. I know that this system doesn't have much memory but it is currently CPU bound not memory bound now that I am running tools. I'm really a novice PC user but an engineer so prob dangerous. If I try to run a couple of IE windows, it's sooo slow. I would appreciate any help with analyzing any logs I can provide. Please help as this

Platform: Windows XP SP3 (WinNT 5.01.2600)
Memory and HW: 768M (Pentium 4 CPU 1.60GHz)
MSIE: Internet Explorer v8.00 (8.00.6001.18702)
Running Norton
Network connection: Wired but connection to Netgear Wireless router

Process explorer shows iexplore.exe with many 1million page faults/huge memory/virual size footprint. The DLL section shows RED sometimes.

Have run HijackThis and have a log
Have Malwarebytes but didn't run it to completion
gmer doesn't show anything.
