I have the exact same problem with an additional one called Sychost which i can't get rid of from the start-up list in msconfig it just keeps on reloading itself, have never had these problems before only since i downloaded Limewire yesterday & dowloaded a couple of music files, now even after countless scans by Norton & 3 spyware removal utilities i am at my wits end.

Even though i have un-installed Limewire that too keeps on loading itself on to my my screen.

Any help would be most appreciated.
