Unrelenting Error Message

I keep getting an error message as follows:

"Internet Explorer has encountered a problem and needs to close. We are
sorry for the inconvenience.
_______________________________________

If you were in the middle of something, the information your were
working on might be lost.

Please tell Microsoft about this problem>

We have created an error report that you can send to help us improve
internet explorer. We will treat this report as confidential and
anonymous."

To see what data this error report contains, Click here

(Then there are two buttons) Send Error Report and Dont't send.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I never send it because I do not trust the message. However, where I
used to just hit "Don't Send" I could go on with using the computer as
if the message never occurred. Now, however, I cannot go online for
anything and the window always comes up, and it will not go away.

When I "click here" the error signature is:

AppName: iexplore.exe
AppVer: 6.0.2899.1106
Mod Name: winshow.dll
ModVer: 1.0.0.1
Offset: 00009901

The following files will be included in this error report:

C:\DOCUME~1\LOCALS~1\Temp\WER773.tmp.dir00\appcomp.txt

^^^^^^^^^^^^^^^

Can anyone explain how I can fix the problem? What is the problem?
