Security experts selling weapons to ward off the dreaded Conficker warned anyone who would listen that April 1 could be a day of destruction, as millions of infected machines started phoning home for malicious software updates. Of course, not only was April Fool’s Day a non-event for Conficker, but now comes news that there are far fewer than millions of systems infected with this version of the worm. Earlier in the week Security Fix reported that only six percent of the world’s Conficker-infected systems are in North America, let alone the United States. On Thursday, the researchers who brought us that news – from Atlanta based Internet Security Systems – published their best guess of how many Windows systems are infected wtih Conficker.C, the only version of the worm that instructs computers to search the Internet and private P2P networks for updates after April 1.
