From the linked article.

"NEVER use a three prong to two prong AC adapter to fix a ground loop problem. These devices are meant to provide a safety ground (via the cover plate screw to a grounded outlet) in the event a three prong plug is used with a two prong outlet. It is always best to lift the ground safely at line levels."


Alan has a good article on ground loops here.
