Hi ngolden,
I am going to leave the WPFind Log analysis to PP, that is definitely not my area of expertise (if I have any area). Several things I notice in your HJT logs though...
You are running eTrust® Internet Security Suite. This is fine but hope you know it does include a firewall. Have you disabled the Windows Firewall?
You have a lot of items running unnecessarily at Start Up and therefore in the back ground...these items could slow the computer also;

WD Button Manager>>>>Button manager installed with a western digital external disk drive. Allows you to back up your system with one click. This is up to the user whether it is needed to run all the time.

iTunesHelper>>>Installed with Apple's iTunes for Windows. Uses ~3-4MB of memory and if disabled in MSCONFIG or deleted from the registry it will re-instate itself after running iTunes a few times. If you do not use this, then I would try to disable it.

QuickTime Task>>>System Tray access to Apple's "Quick Time" viewer from version 5 onwards

TkBellExe>>>Application Scheduler installed along with RealOne Player. Once installed, it runs independently of RealOne Player
PrinTray>>>Lexmark/Compaq printer icon in the System Tray for quick access. Not required - uncheck via Printer configuration rather than MSCONFIG. See also LexmarkPrintray and CompaqPrinTray
HP Software Update>>>does not need to run all the time. Can be run manually

QOELOADER>>>anti-spam tool for Outlook/Outlook Express. Required when supporting OE but not for Outlook. Shortcut available via Start -> Programs

MSMSGS>>>Windows Messenger utility. If you don\'t use Windows Messenger, this can be annoying. Available via Start -> Programs. Go to Windows Messenger > Tools > Options > Preferences and uncheck "Run this program when Windows starts"

Adobe Reader Speed Launch.lnk>>>Speeds up the time it takes to load the Adobe_Reader application. Your choice, but not required for Adobe Reader to function properly

Also these items can be fixed with HJT by running a new scan and placing a checkmark next to them;

O9 - Extra button: PartyPoker.com - {B7FE5D70-9AA2-40F1-9C6B-12A255F085E1} - C:\Program Files\PartyGaming\PartyPoker\RunApp.exe (file missing)
O9 - Extra 'Tools' menuitem: PartyPoker.com - {B7FE5D70-9AA2-40F1-9C6B-12A255F085E1} - C:\Program Files\PartyGaming\PartyPoker\RunApp.exe (file missing)
Once you have placed the checkmark then click the FIX button and exit HJT.

I think I am with 3 of 7 here about uninstalling Spyware Doctor. While the program itself is ok, I have seen some people have problems with it.
Personally I recommend using SpywareBlaster and SpywareGuard, both recommended with links in PP's PROTECT YOURSELF FROM MALWARE: Tools & Tips

I am sure he will also get back to you soon with his analysis of your WPFind log.
