NO No No don't leave, here is the link to uninstall it. If you have windows xp it will put it back on when you sign off for the night. You start out with it installed in the morning and I leave it on until night when it is even slower and uninstall. It doesn't take long at all. You can't get videos but you can at any time you have it installed. I book mark this page when it comes up so I have it handy.
