kazaa is nice for finding mp3
but quite tough for finding software
never used wine ........ i either use windows or linux .... i dont like emulators
i dont care that much about virusses .. i am a bit careful .. and whenever i might obtain a virus from somewhere (most of the times because someone else opened an attachment from an email with a .scr file attached

)
(very hard to make them understand that curiousity isnt that healthy on the internet

)
ah well .. whenever i do get a virus .. its just time to do a format and reinstall everything
(thats a very good idea to do with windows about once a year

)
(and i never had a virus on my linux (yet))
