Removing the GAOBOT Worm Note: You must have administrative rights to run this tool on Windows NT/2000/XP. The first step to removing GAOBOT from your computer is to download FxGaobot.exe (http://www.columbia.edu/acis/capture/novargfiles/FxGaobot.ex e) and run it on your computer. Below are a summary of the instructions provided by Symantec for running the tool: Save the file to a convenient location, such as your downloads folder or the Windows Desktop (or removable media that is known to be uninfected, if possible ). Close all the running programs before running the tool. If you are running Windows XP, then disable System Restore. To do so, go to "Start", and select "Settings" and "Control Panels". Open the "System" control panel and click on the "System Restore" tab in the "System Properties" window that appears on your screen. Check the box "Turn off System Restore on all drives" and click "OK". CAUTION: If you are running Windows XP, we strongly recommend that you do not skip this step. The removal procedure may be unsuccessful if Windows XP Sys tem Restore is not disabled, because Windows prevents outside programs from modi fying System Restore. Double-click the FxGaobot.exe file to start the removal tool. Click Start to begin the process, and then allow the tool to run. Restart the computer. Run the removal tool again to ensure that the system is clean. If you are running Windows XP, then re-enable System Restore. If you are using Active Desktop, you may need to restore it. Important Note: If, when running the tool, you see a message that the tool was not able to remove one or more files, run the tool in Safe mode. Shut down the computer, turn off the power, and wait 30 seconds. Restart the computer in Safe mode and run the tool again. All the Windows 32-bit operating systems, except Windows NT, can be restarted in Safe mode. For instructions on restarting the computer in Safe mode, follow the link to the Windows Safe Mode Page (http://www.columbia.edu/acis/security/howto/remove/safemod e.html) . Once you have completed the process and verified that your system is clean, please contact the AcIS Computer Support Center at x4-1919, and give the technician either the Ticket number or the MAC Address displayed on the previous page in order to receive the most prompt restoral of your Internet connection. IMPORTANT NOTE: Running the removal tool is not 100% guaranteed to remove all of the malicious software from your computer. If your machine becomes quarantined again after this problem is resolved, you will be required to reform at the machine and rebuilt it from scratch. There will be no exceptions to this policy, as it is necessary to protect the computers running on the Columbia University network. Thank you for your understanding.
