Thousands of computer users woke up this morning to no Internet access. Following repeated warnings of the looming July 8 end of a temporary fix to a malicious software scam, the FBI said this morning that it still may not be too late to save an infected PC.
It's estimated that millions of computers were infected with the so-called "Internet Doomsday" virus used in the hacking scam, which pushed Internet searches through DNS servers used by the scammers. Law enforcement estimated that by the time they caught the Web crooks, they had netted $14 million in bogus advertising revenue.
According to security experts, more than 300,000 computers remained infected as of June 11, including 69,000 in the United States.
Internet providers including AT&T and Time Warner Cable made temporary arrangements so that their customers would be able to access the Internet using the address of the rogue DNS servers. And the problem, security experts said, was relatively easy to fix.
Online security firms, Facebook and the FBI offered free diagnostic checks for users whose computers may be infected:
