boot virus

As can be seen from the name boot virus, it is a virus that infects the boot sector offloppy dis ks or the Master Boot Record (MBR) of hard dis ks.

Boot viruses overwrite important information for booting, so that the operating system can no longer be started. They take over the startup function and the role of the boot routine and replace the start in the Master Boot Record and earlier in the boot sector on floppy disks. Boot viruses were the most common viruses in the 1990s, they were particularly persistent in that they could also be transferred to floppy disks that did not have a boot sector and could be copied to any floppy disk unnoticed.
