rest active x security?

Hi guys I have a small problem, I cant alter the security in windows xp. As such I cant download windows updates or use any online virus scanners such as bitdefender etc .. because they all need active x to be set at certain levels.
Any ideas how i can force this to happen? using internet options allows me to change them but the new settings just dont remain, it always reverts back to the high settings.
many thanks
