nk497 writes "The FBI is set to pull the plug on DNSChanger servers on Monday, leaving as many as 300,000 PCs with the wrong DNS settings, unable to easily connect to websites — although that's a big improvement from the 4m computers that would have been cut off had the authorities pulled the plug when arresting the alleged cybercriminals last year. The date has been pushed back once already to allow people more time to sort out their infected PCs, but experts say it's better to cut off infected machines than leave them be. 'Cutting them off would force them to get ahold of tech support and reveal to them that they've been running a vulnerable machine that's been compromised,' said F-Secure's Sean Sullivan. 'They never learn to patch up the machine, so it's vulnerable to other threats as well. The longer these things sit there, the more time there is for something else to infect.'"
