I use Azureus to download and i'm still kinda new to the whole thing. I have a few questions about different issues though. I use peer guardian while downloading but it slows my computer down more than i think it should. What other programs are out there that are a good alternative? Also, i've been reading about security and it sounds like a firewall is a good idea. Is zone alarm good enough or would someone like to recommend something better? Is a peer guardian type program and a firewall good enough protection or do I need more? I've been reading alot about security while downloading and I understand there is nothing 100% secure, just wondering what the experts have. Finally, I was wondering if regestering with a tracker is a good idea. I generally don't download music, but rather MUCH larger files. This is a pain in the ass 'cause it's always more leechers than seeders. I noticed that people who are registered with some trackers get to download the files i want with fewer leechers than seeders. I ask this question because I have yet to be dazzled by the speed of downloading with these clients.
