congratulations, it is an Adware.

nothing to worry though.
do this:- ( a quick fix )

Turn the Mesenger Service off (disable it).

start -> run -> service.msc -> ok

Then scroll down to "Messenger", right-click, select properties, and then stop it and and saet the "Startup type" to "disabled".

This will stop those annoying windows popups.

scan ur pc and delete the adware.
Install a good Firewall.
