InfoWorld: On June 10, Google researcher Tavis Ormandy revealed a flaw in the Windows XP Help and Support Center which leaves PCs vulnerable to attack. At first, few hackers were exploiting the vulnerability, but in recent days, the number of attacks has grown significantly. According to Microsoft, 10,000 users have now complained about the attack.
An advisory on Microsoft's Web site explains how to turn off the Help and Support Center to avoid attack. The next "Patch Tuesday" is July 13.
