Slow Explorer.exe

Hello,
This is my first time here, or, actually, on any forum, so I will apologize advance for any etiquette miscues. I have noticed that Windows XP, at least on my machine, runs much slower than Windows 98. I usually have several WordPad documents open at a time, flipping back and forth, and using voice-recognition software. Windows 98 will open a new WordPad file almost instantaneously, while sometimesI have to wait almost 10" in Windows XP. According to Task Manager, explorer.exe is using greater than 90% of resources for this whole time. I have "cleaned" the machine (Delldimension 2400Pentium 42.2GHz CPU, 768MB RAM, 30GB hard drive) as best as possiblewith updated versions of Norton antivirus, Spybot S&D, AdAware, "by the numbers", as well as deleting temporary files and cookies, following the advice from such Internet site as TexRussand "Fix, Tweek, and Clean". Finally, I run a HijackThis scan and have included the log. Thanks in advance for your help
