A new virus targeting flaws in Microsoft's Windows operating system is circulating on the Internet.
The Zotob virus is said to exploit security holes in Windows 95, 98, ME, NE, 2000 and XP platforms and can give hackers remote access to affected systems.
Microsoft reported that although reports claim that Zotob was spreading rapidly, its impact has actually been limited because it targets Windows 2000, an older version of the software. It poses no threat to computers running the newer Windows XP and Windows Server 2003, the company added.
