How to remove boot viruses

WHAT IS A BOOT VIRUS?

An MS-DOS virus infects the boot record program on hard disks and floppy disks or the master boot record on hard disks.

The virus gets loaded into memory before MS-DOS starts and takes control of the computer, thereby infecting the computer when the computer is booted from an infected disk.

A boot virus may make it impossible to start the computer.

You can read more on what boot viruses are in the box to the right. This guide will show you how to remove boot viruses.

Please follow the guide below:

For Windows XP users
For Windows Millenium and Windows 98 users

Recovery Console

Please use the "Recovery Console" for Windows XP to fix the infected boot sector.

To install the "Recovery Console" as a startup option, please follow these steps:
- While Windows is running, insert the Setup CD into your CD-ROM drive.
- Click Start and select Run.
- Type the following command, where D: is the CD-ROM drive letter: D:\i386\winnt32.exe /cmdcons
- Follow the instructions on the screen.

Note: The Recovery Console is designed to help you recover your system when your computer does not start properly or does not start at all.

Reboot system

Please reboot your system and keep pressing F8 before the loading screen of Windows appears (if you see the logo of Windows you'll have to reboot again).

Select the "Recovery Console"

From the menu select the "Recovery Console".

Once the "Recovery Console" has started you will have to choose which installation you want to log on to (if you have a dual-boot or multiple-boot system) and you will have to log on with your administrator password (if it is the case).

Please input the following commands in this order: fixmbr and fixboot .

That's it.
