Some activex applets and elements are used for some nefarious ends. It MUST be corrected.
ANY obsolete and unused item can be suppressed safely, but nothing wrong will appen if you don't do anything.
If any diagnostic utility ever ask you to pay to upgrade to the full version in order to rapair the found problems, DON'T EVER PAY ANYTHING! That's an absolute sign that it's a rogue scanner. If you pay, it WON'T repair the "problem" as there realy was no real problem found, but instead, it may install some realy nasty things.
