Avrum, if you want to find out more about the sponsor program you can search the forum and you will definitely find loads of stuff.
The following is from the Messenger plus! website.

Messenger Plus! comes with an optional sponsor program (for more information about the sponsor, please visit the Get The Facts page). This program will show ads from time to time on your computer, will add a search bar in Internet Explorer and will also change your start page. In NO case this sponsor is mandatory or dangerous. If you don't want it, simply refuse the sponsor agreement during the setup and you will never hear about it again. If you installed the sponsor by error, just uninstall Messenger Plus! (it will trigger the sponsor uninstall program), reboot your computer, and reinstall without the sponsor if you want to continue to use Messenger Plus!.
Important: if you wish to get rid of the sponsor program, you must uninstall Messenger Plus! from the Add/Remove Programs window. If you start deleting files on your own you will prevent a full system restore as some of the files copied by the sponsor are backups of your original configuration files. Also, never attempt to use programs such as Adaware to remove the sponsor. Doing so would permanently damage the sponsor's restore data and would make the uninstallation much harder than it should be. You don't use third party programs to remove your other software, the sponsor is no different. For detailed instructions, check out this special post on the forum.
Another great site with info about and how to uninstall the sponsor is here.
