Iunno I couldnt find my stuff on the main 2 sites I use pirate bay and isohunt so i searched the cds name and found it on some torrent site called btjunkie, is there anymore risk in getting torrents from different sources or whatever? maybe btjunkie is pretty common anyway?

It's all much of a muchness. Just scan the file before opening it.

if you mean virus-type security, well, just be careful what you click on hose sites, and scan teh fies.
If you mean risks of getting caught downloading, then stick with private trackers (waffles, what.cd, libble, etc) rather than public ones (like isohunt and Pirate Bay).
