When does this happen? At any time or only when you open IE?
This is an error message which usually results from out of date Java so update that and see if the pop up stops, er, popping up.
The first thing to do is uninstall any old versions of Java on your machine. There are instructions here:

Then install the latest version of Java which is here:
