 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 he box to the right. This guide will show you how to remove boot viruses.

 

Please follow the guide below:

2- button  Use the DOS utility

 

 


The boot sector must be replaced using the DOS utility FDISK.EXE:

 

- Switch off the PC, wait several seconds then boot from a clean system disk (to prevent the virus from being loaded into memory).
- At the command prompt type: DIR C:
- Check that the contents of the infected drive are visible. If they are not contact support for advice.
- To overwrite the master boot sector enter FDISK /MBR

 

Note: If you don't have a clean system disk, you can get create one by following this link:
