Sonia,
I'm sorry but I must be like a car driver who has no idea what the engine is!
I've read the articles and still don't know if or how I can work around the
problem. The articles talk about what one can do with chm files (does Excel
help for example come into this category?) but I don't get any options to do
anything - just a message saying IE cancelled the action. So sorry to be
frustrating!
In programs such as those in the Office 2000 suite, the help files are
stored locally as compiled HTML Help (.chm) files and are not out on
the World Wide Web. So the error messages you're seeing are a little
misleading, borne of the fact that the HTML Help format uses Internet
Explorer to display the help content.
Are you accessing these programs and their help files over a network?
If so, the problem is caused by the 896358 security update, but the
workarounds are as described in these articles:

Or see

description of the issue.
If you continue to have problems, it would be worth running MJ's Help
Diagnostics, which is available from here:

This will check that all the components required to display HTML Help
files are properly installed on your machine.
