Microsoft Says Recovery from Malware Becoming Impossible

"Danseglio said malicious hackers are conducting targeted attacks that are 'stealthy and effective' and warned that the for-profit motive is much more serious than even the destructive network worms of the past. 'In 2006, the attackers want to pay the rent. They don't want to write a worm that destroys your hardware. They want to assimilate your computers and use them to make money.

'At Microsoft, we are fielding 2,000 attacks per hour. We are a constant target, and you have to assume your Internet-facing service is also a big target,' Danseglio said."
