Hi Phil!
Actually there are three Gnutella clients with spytools:
- bearshare
- liwewire (only the free version!)
- swap nut
And the client kazaa is also infected but you can use Morpheus...
Download ad-aware as the others suggested!
why should you use a Gnet client? Very easy...
Gnutella is an other net with other users and other files... so if you use Morpheus "and" a Gnutella client you can find much more files!
