"Microsoft's vice-president Jim Allchin told at a recent Windows Vista reviewers conference a story about chief executive Steve Ballmer: It seems Steve was at a friend's wedding reception when the bride's father complained that his PC had slowed to a crawl and would Steve mind taking a look. Allchin says Ballmer, the world's 13th wealthiest man with a fortune of about $18 billion, spent almost two days trying to rid the PC of worms, viruses, spyware, malware and severe fragmentation without success. He lumped the thing back to Microsoft's headquarters and turned it over to a team of top engineers, who spent several days on the machine, finding it infected with more than 100 pieces of malware, some of which were nearly impossible to eradicate.
Among the problems was a program that automatically disabled any antivirus software."
Well at least, that's true management commitment...
But as Steve is a salesman, I hope he sold at least a copy of Windows OneCare (and installed Windows Defender) ;-)
