If you browse the web using MS Internet Explorer, you should know that attack code has been published on publicly accessible websites that allows attackers to take control of your PC. MS is investigating, no word on when a patch will be made available.

IE versions 5.01 and 6 on all current versions of Windows are affected, the French Security Incident Response Team, or FrSIRT, a security-monitoring company, said in an alert on Wednesday. FrSIRT deems the issue "critical," its most serious rating. Microsoft noted that Windows 2003 running Enhanced Security Configuration is not affected.
