Google plans to warn more than half a million users of a computer infection that may knock their computers off the Internet this summer.
Unknown to most of them, their problem began when international
hackers ran an online advertising scam to take control of infected
computers around the world. In a highly unusual response, the FBI set up
a safety net months ago using government computers to prevent Internet
disruptions for those infected users. But that system will be shut down
July 9 -- killing connections for those people.
The FBI has run an impressive campaign for months, encouraging people to visit a website that will inform
them whether they're infected and explain how to fix the problem. After
July 9, infected users won't be able to connect to the Internet.
