You'll see them produce a Mac product when the Mac becomes a profitable platform for the virus writers, and viruses begin to appear.
For now, they're just spreading FUD, trying to break down the common assumption that Macs don't need anti-virus software. That's a correct assumption for the time being, because it's so much harder to write a virus for the Mac. Of course the Mac has vulnerabilities, all complex software does, but it's damn difficult to EXPLOIT them, which is why the virus writers avoid the Mac as a target. It's too much hard work!
But that won't last forever -- Windows 7 is pretty damn secure, and people are migrating off the old Win2K/XP platforms. So it will eventually become harder to use Windows for the botnets and so forth.
At that point, the Mac will start to look attractive as a virus target, despite the much greater difficulty of exploiting its vulnerabilities.
And then you will see Mac anti-virus software begin to take hold. Until then, the companies have to stick mainly to Windows, because that's where the profit is. To do otherwise would be stupid business.
You'll pardon me for not joining in these festivities more than I did way above. Unfortunately this thread has taken a familiar turn and I have nothing to add but this meta-observation:
There's an old joke, that among professional comedians, all the standard jokes had become so well known that they were simply cataloged and indexed by number. The pros no longer bothered to tell the jokes -- they just refer to them by number. (I'm sure you remember the rest of this joke and punchline, so I'll just refer to it by number... "47". [Ha ha ha ha...])
Anyway, these threads could be streamlined considerably, with no appreciable loss of content, if we had a catalog of statements and responses, and simply chose the appropriate one for our comment posts. Think of the time saved!
I hereby submit some initial suggestions for the catalog/index:
Cheers! :)
