I read this morning that Microsoft is going to sell an Antivirus product.
The first thing it does is de-install Windows. (buh-dum pah!)
But seriously, I'm certainly not the first to note that this is just a bit like MS charging to fix critical bugs it left in the system. And Dvorak's note about an antivirus tool being a way for MS to get an online footprint on their customers' machines that they can touch weekly is cautionary, especially in context of MS' failed attempt to get in the middle of all transactions their customers conducted on the net (remember Passport?).
MS still wanna be Big Brother. At least the taxation part of that.
