I'm not sure I can go along with that interpretation -- A virus, in order to be a virus, must traverse from computer to computer -- and a worm does the same thing, but directly, without intervention or carrier (email message, etc).
hmm that is confusing. your saying that a virus goes from computer to computer WITH user interaction, and a worm goes WITHOUT interaction (from the user, via whatever means)?? right??
which is what i said...... so please verify - im not seeing us having a problem with this issue..
What did you manage to download, and what did it do (he asks curiously)?
it automatically started downloading off a website, it was a dmg file, it had a very suspicious name of the dmg. luckily, i managed to hit the "stop" button before it finished downloading.. who knows what it would have done if it expanded itself. this was back in the Tiger days when programs on dmgs could run without being warned.
It's a fine hair to split, and we're playing semantics. Point being, pending receiving further light and knowledge, I stand pat - there are no true viruses (or worms) as of yet. That's not to say there's not malware, disguising itself as one thing while it is really evil.

personally i believe that there are MOST definately mac viruses/worms/trojans roaming the internet, there HAS to be. but i have no proof (i cant visit every website
