They seem to be talking about the automatic update...not the full install but I just posted about it on the thread...

Hello, I'm from Messenger Plus! Community forums and I'd like to point out some things about the sponsor program.
The sponsor program isn't the usual ad-ware crap you see around on the internet. It's specifically designed for Patchou (creator of Messenger Plus!) not to be intrusive. Attempting to remove the sponsor program by anti-spyware tools or just deleting it isn't the way to go about it. You must uninstall Plus! and re-install it and deny the sponsor program (I attached an image).
If you have installed the sponsor program and have tried to remove it by anti-spyware or deleting it manually you will need to re-install Plus! with the sponsor program and then uninstall it and then re-install it without the sponsor program...

I hope this experience hasn't discouraged you from using Messenger Plus!
