Update Now to Fend Off Latest Worm and Variants

This news item expired August 31, 2005. It may contain out-of-date information.
Risk assessment for the W32/IRCbot worm/virus has been raised to Medium because of increased reports. This worm is another variant of the W32/Zotob Internet worm, spreading by exploiting the Windows Plug and Play vulnerability (see for details).

This worm will execute on Windows 95, 98, ME, NT 4.0, 2000, and XP machines, but will only infect Windows 2000 and unpatched Windows XP computers (XP Service Pack 2 with the latest updates should be safe). Vulnerable machines can be compromised over the network, or the worm may be run as a Trojan horse.

Protect your computer by ensuring you have the latest Windows updates installed and your antivirus package is also up-to-date. If you have questions or need assistance, contact the Solution Center by phone at 515-294-4000, email at , or in person at 195 Durham Center.
