To remove this virus, boot the computer from a Norton AntiVirus Rescue Disk and then run a DOS scan:
- Shut down the computer, and turn off the power. You must turn off the power to remove the virus form memory.
- Do one of the following:
- If you have recently created a Rescue Disk set on the computer that is infected, and you updated the virus definitions before doing so, go on to the next step.
- If you do not have a Rescue Disk set that contains recently updated virus definitions, you will have to create a Rescue Disk set on an uninfected computer. Skip to the section To install and create Rescue Disk on an uninfected computer.
- Insert disk 1 of the Rescue Disk set (the boot disk), restart the computer, and follow the prompts to scan the hard drive.
CAUTION: If you are using a Rescue Disk set that was created on another (clean) computer, and you see a message similar to:
"Your Master Boot Record (critical startup information) has changed."
Do not choose the option to update or change the Master Boot Record. Doing so will overwrite Windows files with information from the computer on which the Rescue Disks were created. This can cause the computer to stop functioning. Make sure that you use the Rescue Disk only to repair viruses. Do not make any changes to the operating system.
- If Norton AntiVirus cannot repair the virus, you may need to need obtain the services of a qualified computer consultant.
To install and create Rescue Disk on an uninfected computer:
Requirements: Five or more blank 1.44 MB floppy disks and a Windows 95/98 computer that is not infected by a virus.
- Install Norton AntiVirus on an uninfected computer that has the same operating system as the one that you are trying to clean.
- Run LiveUpdate to update the virus definitions.
- Follow the instructions in the section "Updating Rescue Disks" (or similar title) in the Norton AntiVirus User's Guide.
- Return to step 3 of the previous section.
