file extentions

[helpless1]

My daughters internet connections is working fine, but when she tries to use internet explorer or her other programs it keeps saying, "this file does not have a program associated with it for performing this action.  Create an association in the folder control panel. Which extention would that be and how do it do it? Any ideas?

I know this is the most common response in here but it is also the most common problem.
Scan, start here first.
