messenger plus doesn't have any virus's and anything that will harm you computer. it does how ever come with an adware sponsor program, which you have the
option not to install, that will add a toolbar to your internet explorer and change your homepage.
if you have installed the sponsor program and don't want it on your computer do not try use programs like spybot search and destroy or ad-adware, because these programs do not kno how to uninstall the program. use the insturtions given on this site
