Getting unwanted messages from unknown individuals or spammers is truly a headache. Some of these messages are a virus carrier. If you are getting net send spam (unwanted message box’s) then you can stop this by right clicking “my computer” go to manage, go to services and applications > services, then locate the service called “messenger”, go to its properties and disable it in the drop down menu and apply. This is not msn/windows messenger, these just blocks incoming net send messages through dos and will stop net send spammers. You will surely get a headache-free every time you open your mail.
