After trying to remove a program using the Control Panel,
Add/Remove Programs, I now receive an error message when I
try to start up my computer in regular mode or safe mode
and the desktop icons never come up.  

The error states:
Explorer performed an invalid page fault in module
Explorer.exe at 0197:00401f31

it goes on to specify Register and Stack dump information.

The first time I restarted my computer after trying to
remove the program, Windows took me through the setup,
where I had to enter my product ID and accept the Window's
agreement before starting up and then I login as usual but
receive this error message soon after and icons for the
desktop never come up.

The program I removed was a random search tool that I
unintentionally accumulated from the internet.

Please help! -Phil
