Live Advert Remover (formerly known as MSN Advert Removal) works with all versions of Live and MSN Messengers. You need to run it only once to "patch" your system.
However, this program can’t remove Live Messenger default banner ads. It will remain intact, but it will never be replaced by any commercial advertisement. Also this program does not remove any advertisement provided with Messenger Plus! extension.
