Outlook in Office 2003 keeps shutting down

Yesterday when opening Outlook 2003, it showed an error and offered to
report to MS. I managed (I think) to get rid of the fault by going to
a previous restore point). Fingers crossed!

My other computer has now started to do the same thing. I am going to
try a couple of restore points. ( 2 failed to work).

A search found a CWS INFECTION can produce that sort of fault. I have
tried that fix but it does not seem to work. Used a CWS Shredder
program.

Any ideas
