You forgot that Vista is a Virus
it even starts with a V
Virus Inside Switsh To Apple
And no, it is not Virus save like microsoft pretendes to say
Vista has the same viruses like xp has, but the defender works in one way... it still is really annoying.
OS X has some trojan, too.
2 as far as I know, but it's hard to get them
first they are not spread all over the internet like windows viruses, worms ans trojans are
second is that you need to install them manually! YES, YOU HAVE TO ALLOW THEM TO RUN!
to get such a trojan you need to confirm the installation with your root user and 2 passwords...
that's some kind off odd if you ask me and I'll never install a so called "codec for quicktime" because quicktime has no codec plug-ins, it get's all codecs with the newest version ^_^
