Free of spyware?

As I recall DC++ is not an easy one to figure out.  I'd also recommend Avast for a virus scanner so you don't have to worry AS much.  Though always becareful with anything you do.  You can obtain avast from here Spyware Removal Go to Virus Removal Link on the left, then Step 5.  (if you don't have a virus scanner).  You are always going to be at risk for viruses anytime you are sharing files.  Though kazaa obviously comes with a ton of included garbage and you'd want to avoid that.
