for some reason, whenever i close limewire, it'll just start up by itself after like 5 seconds...this just starting happening very recently...ive tried uninstalling, then reinstalling, but it didnt work...ive restored the options to its default...i unchecked the "startup when windows starts".....anyone have an idea about whats going on?!?!

It's a virus. See point 4 here
