Worm Alert

Recently, a significant security vulnerability has been discovered within Windows NT, 2000, and XP. A certain worm virus called MSBlast or Lovsan will exploit the security vulnerability unless your Windows system is updated immediately with the appropriate security patch.

It is our strong recommendation that you install the security patch to prevent a potential attack to your computer. Below are three sets of instructions that step you through the process of applying the necessary security patch to resolve the described vulnerability and how to apply other recommended critical update patches for your computer.
