An online banner advertisement that ran on MySpace.com and other sites over the past week used a Windows security flaw to infect more than a million users with spyware when people merely browsed the sites with unpatched versions of Windows, according to data collected by iDefense, a Verisign company.
Ouch. This only affected anyone who was using Internet Explorer, but it’s estimated that over 1 Million users were infested. If you don’t have the latest Windows updates, now would be a good time to grab them.
