When you have installed Plus with the sponsor, you can just go to uninstall Plus, when it first comes up to uninstall you can get an option to uninstall the sponsor. Just uninstall the sponsor from the option there and it is gone.
The sponsor program, I assure you is just a little bit of optional adware that will do no damage, not spying on your computer, no hacking to your computer and no virus!

If it did contain this and everyone got it, it would seem logical that there would be loads of warnings about the software, that haven't been proven as wrong. If you still believe there is a virus in Messenger Plus, why don't you e-mail McAfee, Norton or go on another technical help forum and ask. Not hundreds of people would actively lie about it. And there's loads of people who use Plus, chances are you will have a contact or know someone who uses it without problems.
