”Symantec, though its assisted enquiries from investigators, has said it would rather take on Microsoft in the marketplace than cry foul to regulators over Microsoft's entry into the consumer anti-virus marketplace. McAfee has made no suggestion it's about to object to Redmond's encroachment on it traditional turf, either. So it seems Microsoft has either decided anti-virus technology is better delivered as a service or else figured out that's a better business model to pursue.”
Let's hope that an average user hearing news about “no anti-virus for Vista” doesn't take it to mean the OS will be unprotected. Then again, OneCare is still a long ways off from a Vista version so we have yet to see how well it performs. Odds are, there will still be plenty of room for anti-spyware and other 3rd party software.
