Although computers running Windows Vista are significantly less likely to be infected with attack code than machines running Windows XP, the newer operating system continues to be threatened by Microsoft Corp.'s own ActiveX browser plug-in technology, according to a report issued Monday by the company.
In the most recent installment of its twice-yearly security intelligence report, Microsoft said that PCs running Windows XP Service Pack 2 (SP2) were more than three times as likely to be infected with malware as computers running Windows Vista SP1. Machines powered by the newest XP security update, SP3, meanwhile, were more than twice as likely to be infected.
