Microsoft said that the site had been subjected to a denial of service attack, according to Network World Fusion, but it wasn't anything to do with the Blaster worm or the power down in the US.
Yeah right! Trust Microsoft? I think not. Blaster was created to do a Denial Of Service (DOS) attack on www.windowsupdate.com today. Why lie?
If you have to use Windows, which I often affectionately call WinBlows, WinDoze or WinDOH!ze, be sure to check http://www.windowsupdate.com regularly to plus the millions of security holes and fix the millions of bugs that are rampant in every version of Windows. And make sure you update your virus protection AT LEAST every month. If you cannot set it to do so on its own to check weekly, do so manually. Its the best protection against viruses other than to never open attachments from people you do not know and never open .exe files that you get via email even if it is a trusted source. The person could simply be infected with a virus and inadvertently sending you a copy of said virus.
But, if you can afford it go to MacWarehouse Computer Stores and buy yourself a new Apple Macintosh Computer. You may miss the fun of constant virus scares, the blue screen of death and persistant crashing, but the simplicity and power more than make up for that inefficent fun of losing files that you will miss out on. :-P
