I've got this ****e on my system somehow too and I have absolutely no idea how it got on here, I am very careful about what I install on my computer. I first noticed this junk when right clicking on windows media player this morning to jump start one of my play lists. I've not used it for a few weeks but it used to work fine, now I get this irritating pop up asking me to register and you cant close the window for 80 seconds and you cant minimise it either. Very bloody irritating.
I've noticed that right clicking on my computer and selecting manage bring this pop up up as well
