Under your Help, regarding passwords, you recommend having an antivirus.
You should make note of the exception for those using Linux based systems. They're pretty much hack-proof systems after all. Even trying to find an antivirus for those systems are pretty much like finding a needle in a haystack. Stating that people should have an antivirus may make new users to Linux waste a lot of time trying to find one when it's not needed, if they keep their systems up to date.
