I used linux. It is very good OS. But it's quite hard to use it (if you are a new 1). I used: Mandrake, Gentoo, Slackware, Red Hat (Now known as Fedora CORE), Debian, Knoppix, Kanotix, Baltix and some others Unix-Like OS (FreeBSD, NetBSD)....I like them. They are safe and PHR33! :)) P.S. I know only 2 Keyloggers for linux. P.S.S. Linux uses Multi-Users system so there is hard to work for the programs as Viruses, Troy Horses and other bad soft ;]]
