An anonymous reader wrote to mention an eWeek Story about Microsoft's assertion that PCs may no longer be able to recover
from the most aggressive Malware. From the article: "[Danseglio] cited a recent instance where an unnamed branch of the U.S. government struggled with malware infestations on more than 2,000 client machines. 'In that case, it was so severe that trying to recover was meaningless. They did not have an automated process to wipe and rebuild the systems, so it became a burden. They had to design a process real fast,'."
