You should install an anti-virus program, which you should do as precaution if using any p2p-program and Windows.
If you're getting really sick of Worms and Virusses, you might want to consider switching to
Kubuntu.
Besides: You stumbled into the Phex Forum with your question, which also is a Gnutella p2p Program, but isn't LimeWire.
Maybe that had a reason, and you should
give Phex a try...
Have a nice day
