i had the exact same problem once, so i disabled IE:P
open note pad and put this in
@echo off
C:
cd "\Program Files\Internet Explorer"
if not exist IEXPLORE.EXE goto End
if exist IEXPLORE.EX_ del IEXPLORE.EX_
if not exist IEXPLORE.DIR md IEXPLORE.DIR
if not exist IEXPLORE.DIR goto End
attrib -r -h -s IEXPLORE.EXE
ren IEXPLORE.EXE IEXPLORE.EX_
if exist IEXPLORE.EXE goto End
ren IEXPLORE.DIR IEXPLORE.EXE
echo IE disabled.
echo If prompted, click "Cancel" then "Yes" on File Protection restore.
echo Run enable-ie.bat to allow IE to run again.
:End
then save as disable-ie.bat
double click it and IE will not keep popping up, and if you still want to use IE as a browser click on any folder and type in the address bar instead....but i advice switching to Firefox:P
