Virus Alert : Windows PC Customers - Important Problem
Customers may be experiencing Continual shutdown/reboot, and/or slow browsing

To All SNET Internet customers,

Recent viruses (known by names such as Zotob, Esbot, etc.) have exploited vulnerabilities in Microsoft Operating System functionality (MS05-039). These viruses cause continual rebooting of machines (infected machines), and/or slow browsing (carrier machines).

How to Tell If Your Computer May be Infected

  • Your computer is constantly rebooting when attempting to connect to the Internet or on system startup. This means your computer may be infected with the virus and will not perform properly.
  • Your computer's performance has suddenly degraded and is running very slow. This means your computer may be carrying the virus without significantly impacting your connection.

How to Fix the Problem

  1. To stop the shut-down in progress, follow the following process:
    1. Left mouse click on Start
    2. Left mouse click on Run
    3. Type cmd and then click OK
    4. Type shutdown /A (WIN 2000/NT 4.0) or Type shutdown -a (WIN XP/2003)
    5. Press Enter
  2. How to patch the vulnerability:

    Visit Microsoft's Website at:
    http://www.microsoft.com/technet/security/bulletin/MS05-039.mspx

    Select your Operating System, download and run the patch

  3. How to remove the Virus:

    If you have an antivirus program, update your definition files

    • Norton - Right click on the Norton Icon in the system tray and select "Norton Updater"
    • Mcafee - Right click on the Mcafee Icon in the system tray and select "Update"
    • Yahoo Online Protection - Click the update button upon launching Antivirus program
