In XP/IE6 -

I keep getting the pop up warning 'Cick to allow Active X controls on this page.'

It just started doing this.

Where do I turn it off?

These are my settings:

PC recently cleaned down, XP reinstalled, Norton installed.
IE settings: 'allow Active X controls' on.
Norton Firewall settngs: Medium, i.e. allow Active X.
Something called 'Windows Defender' installed now, althougy I never saw it before the clean-down.
