I'm pretty sure bearshare has adware and instead of bearshare would like to recommend limewire which has no spyware/adware. (has limeshop but that's easily removable).
NO NO NO NO NO!!!!!!
sorry *composes self*
Bearshare is riddled with spyware (call it adware, what you will, it's spyware in my book)
So is limewire
If you want limewire, http://www.mp3newswire.net/stories/2002 ... ewire.html
look for clean limewire
personally I found limewire to be poor at best. I use Kazaalite Ressurection (sorry, you'll have to search as Sharman kill sites linking to it) for the k++ functionality plus better connectivity to new KMD clients. I use eMule plus, for my ed2k needs (ie anything that isn't mainstream and likely to be found on the faster fasttrack network or software/disc images which are less likely to be corrupted) and BitTorrent for most of my anime requirements. That coimbination works well for me - and I've not really had as many problems with kazaalite ressurection leaking ram as I used to with older kazaalite clients
