Dell Inspiron 1501 laptop, AMD Turion 64 X2 Mobile, 1.87 GB RAM, 4.5 years old, running XP

I had a malware problem which I've been dealing with over here:
http://forums.spybot.info/showthread.php?t=64275

I first noticed this issue shortly after running one of the early steps in my malware removal (after running Gmer) but it's possible it was present before then. I think the first thing I noticed was the boot up time. When I reboot, it seemed to hang on the XP welcome screen, but finally got to the log in screen. I couldn't actually click to log in though for a minute or 2, and then... well, the whole boot up from start to finish was over 15 minutes.

The task manager showed that the idle process was 95-99 but CPU usage was at 40-50 (even 60). I downloaded Process Explorer which was showing that all that unaccounted for CPU usage was "Interrupts". What does that mean? Is this due to a bad hardware component? a bad driver? How do I get more information on this?

My suggestion would be to first resolve you posted malware topic...before moving on to worrying about system performance. IMO, the existence of one impacts the other.

Actually, I probably could've worded it better but, the malware problem is essentially resolved. In fact, in that linked thread, the tech who was helping me advised me to post in another forum about this (potential) driver issue and then come back to remove all the anti-malware software and logs and stuff.

So that's where I'm at.
