YSB Toolbar
What does it do? We don't have a lot of information about it yet, but we do know that it restarts Shareaza after the user shuts it down, probably as a way to spread itself more efficiently on the network.It is probably installed by the user after it comes up as a result for a random query.
How do i get rid of it? Get either Spybot - Search & Destroy or AdAware, and try it with this.
