NEW YORK (AP) - It's software that is supposed to protect computers and the people who use them from viruses and other rogue programs. But for a time yesterday, McAfee software was the culprit in causing a bunch of business computers to malfunction.
It started when McAfee posted a software update yesterday morning for its corporate customers. Turns out the update made the antivirus software identify a normal Windows file as a virus. And that meant computers running in hospitals, schools and companies began seizing up.
They kept rebooting themselves as the antivirus software gagged on a file that it should have allowed to let run. McAfee has since posted a new update that eliminates the problem.
McAfee says it can't tell how many computers were affected. But based on online postings, the number was at least in the thousands - and possibly in the hundreds of thousands.
