Despite repeated alerts, tens of thousands of Americans may still lose their Internet service Monday unless they do a quick check of their computers for malware that could have taken over their machines more than a year ago.
The warnings about the Internet problem have been splashed across Facebook and Google. Internet service providers have sent notices, and the FBI set up a special website.
According to the FBI, the number of computers that probably are infected is more than 277,000 worldwide, down from about 360,000 in April. Of those still infected, the FBI believes that about 64,000 are in the United States.
To check whether a computer is infected, users can visit a website run by the group brought in by the FBI: http://www.dcwg.org .
The site includes links to respected commercial sites that will run a quick check on the computer, and it also lays out detailed instructions if users want to actually check the computer themselves.
