ME, IE 6, Dell 4100 series. 20 gigabytes hard drive, 256 mb ram.

While on a "Scientific American" website and while SpyDoctor was scanning
for "infections," I received the following message in black on a white
background box:  Kernel 32 caused a general protection fault in module
KRNL386.EXE at 0001.000075a8. My puter was frozen and ctrl-alt-del did
nothing, so I had to use the emergency reboot button.  I suspect this was
caused by SpyDoctor, but I don't know.

Upon start up, I also receive the following messages:  "Internet Explorer
Script Error
Line 20
Char 1
Error object expected
Code 0
url: http://t.msn.com/en-us/default.aspx?ver=7.0.0777&did=1

Do you want to continue running script on this page?"

I click No several times, but the message reappears, sometimes with Line 7
instead of 20.  Last time this happened (after the puter loaded), I had to
click 7 times.  This appears related to an msn site.  Before I was getting
that message, I would receive an MSN newsflash box, together with my hotmail
entries, which I did not want to appear.  So, I downloaded "Startup Cop" and
deleted the MSN site (msnmsgr.exe) from appearing at start up.  However, in
order to access my hotmail, when I clicked on the little pawn in the
Systray, the site automatically undeleted itself from the startup cop menu.
I can live with that, but now it doesn't appear, but these annoying messages
do.
