I've tried to use bearshare (problem with my ISP and P2P) but didn't use the freeserve address there either
Have "Spyware Doctor" installed.
I'm currently reporting each one to SpamCop as soon as it arrives (so many from the same few addresses) but I may just add a "rule" to dump them straight in the "bit bucket". Trouble is that I still have to wait for the cr@p to download!
