I've been getting a bit more concerned about privacy issues as of late and I've decided that I would like to be a bit stealthier online. Now, I already have a copy of Norton Firewall 2004 with it's own privacy thing, but frankly that program seems to be a resource hog-and it doesn't run well on my computer much for some reason. Anyhoo, I was thinking about getting a copy of GhostSurf, but I'd like to save a few bucks if I could. Any suggestions?
