I noticed it said on the Mandrake 10.1 Discovery Page features that its Immune to viruses. Does this mean that 9.1 is immune to viruses too, or only the latest versions? Please see below and notice the underlined text.

My question is, does this apply for Mandrake 9.1 as well?

So let me get this straight, when they mean LESS viruses and spyware in Linux systems, does that mean ALL VERSIONS OF DISTROS or only the latest versions?

For example: If Im running Mandrake 9.1 does this mean Im more vulnerable to viruses than in version 10.1?

Perhaps these will enlighten you.

How about viruses and worms?

"It is virtually immune to computer viruses and other annoyances."

I think the operative word in that advertisement is "virtually". AFAIK, it doesn't have any additional features that make it more "immune" than any other Mandrake release or other linux distro for that matter (although I guess you could make an argument for msec).

What does AFAIK mean by the way?
