Its good that MS is staying on top of things and finding the obscure exploit possibilities long before the hackers do. There's not much to worry about on Windows 7 64bit, all the low hanging fruit from Windows is long gone. Hackers can pick on Macs if they want an easy target. Pro hackers can tear Macs apart in seconds where they can barely phase Vista 64 or Win7 64.
"Writing exploits for Vista is hard work. Writing exploits for Mac is
a lot of fun."
