McAfee has a version of Anti-Virus and ePO for Vista. Not sure about Symantec, but I wouldn't use their stuff for free.
Microsoft, under legal threats, opened the API in October. It's not clear yet whether the PatchGuard for Vista 64-bit (the default install in the next few years) will be opened as well.
Those products from Norton and McAfee have only been running on Vista for a few months at most. They're beta quality at best. And no guarantees that Microsoft won't sabotage them in subtle ways as they've done to so many other competitors in the past.
I wouldn't be buying any Symantec or McAfee stock.
The idea of trusting a company like Microsoft for your security when their own design errors have directly caused the very security problems we face now is just bizarre.
All the real desirable upgrade features from Longhorn were junked because Microsoft simply can't produce complex new technology. Instead, they took the Server 2003 source code, added a couple of puny awkward 3d tweaks and stole Gadgets (Widgets) and Search (Spotlight) from the Mac, made big price increases, forced people to get far more powerful machines or upgrade their current ones, and produced a dizzying array of different versions of Vista. I can't even count how many different "Vistas" they have.
Vista is a sad sick joke of an OS. Its security features will be broken very shortly or already have been, much like the
new hack of their unbreakable HDMI/HDCP protection scheme. Vista will make our security problems far worse than they are with XP.
Vista also is broken on many machines that were sold in the last year as "Vista-compatible". Bad driver support, even for new hardware.
And if Vista is so great, then why are they already planning the release of Vista Service Pack 1 later this year? Another half-baked launch of a product that they'll get around to fixing later? Yeah, like they fixed WinXP SP2 so well.
More FUD crapola from the haters. Don't believe a word of it.
Ironic that M$ fanbois actually accuse others of spreading FUD, Microsoft's favorite tactic to destroy competitors and one they resort to rather frequently because their own technology is so mediocre. Well, I guess if you don't have a chair to throw at people...
When I beta-tested it a few months back in lab, the only things I noticed were different from XP/Server 2k3 was the stupid "pretty-eye-candy" interface and an NT 6.0 kernel.
Other than that, I still think it's little more than XP on steroids...
