RUNDLL32 is not a valid WIN32 application

I have a very weird problem. It started suddenly after 3 8yr old boys were playing on the computer for a few hours. ( I should know better).
Anyway, I run Windows XP Home. I have Norton Internet Security 2003, updated and scans twice a week. I run Spysweeper 3.0. It is update, scans 3 times a week and watches for any unauthorized changes. I also run Spybot and Adaware. With all that "protection", I suddenly get an error message "RUNDLL32 is not a valid Win32 application" when I try to access anything in the Control Panel.  I've tried to look it up on this website and in Google and I haven't found anything helpful.

I'm having another problem that I don't know if it is related. In trying to solve the above problem, I ran Spysweeper, Spybot, Norton Scan (in Safe Mode) and Adaware. Adaware would hang or freeze everytime. I uninstalled Adaware and downloaded the newest version (Adaware SE Personal). It still freezes everytime I run it even if it is running in Safe Mode. I couldn't find any good help at the Lavasoft site. Others have the problem but no resolution exists.

I have already run Adaware (in safe mode). It does not run to completion. It just locks up. So I ran Spybot and Spysweeper instead. There was very little spyware found because I run these all the time. I forgot to mention that I already did run coolwebshredder. I also already ran Panda ONline Antivirus. Nothing was found infected. My MSCONFIG is lean. I keep it very clean.  
The only checked entries in MSCONFIG are:
Hpztsb04.exe (printer)
OneTouch.exe (my external hard drive)

Just fix the above lines and u dont have anything wrong running on ur system Irth :)
So have u tried to check for the problem in Safemode yet ??

try SfC scan.....
Goto START>RUN and type  sfc /scannow
u will need ur WinXP CD in order to fix the corrupted windows system files, if found by scan.

I spent hours yesterday running all the antivirus searches and antispyware searches in safe mode. I had no viruses. There was very little spyware. This did not fix the problem.
When I ran the system file checker, it restored some files and that fixed the problem. I can now access the control panel.

However, Ad-aware still does not run. So, I uninstalled the new version of Adaware(SE). It kept locking up while searching. Adaware found 8 spyware objects but when I cancel the search because it hasn't done anything in 15 minutes, I cannot delete the objects found. I installed the older version of Ad-aware (6.0 Build 1.81). This ran to completion but only found 1 spyware object. I guess for now I'll just keep the older version of Adaware.

SheharyaarSaahil, thanks for your help.
well if u are running fine now..... that's enough :)
