I assume your talking about LW poping back up after you shut it down. If so then you probably have a virus!

There are a lot of viruses being circulated on the network and you have to be careful what you d/l. Especially program files though you can be infected by other files also.

For possible solutions check here: WARNING: Viruses on network you should be aware of! Part 4(a)
and here:Limewire Acting Wierd (PLEASE HELP!!!)
and here: THERE"S SOMETHING that SHOULD not be there

Oh! and next time remeber to use some protection.
