Key notes

As you may already know, amaster boot record(also known as MBR) is a special type of boot sector. TheMBRholds the information on how partitions, containing file systems, are organized on that medium.

In simpler terms, it contains the necessary computer code to start thebootprocess, making it quite important.

Unfortunately, theMBRisn’t safe from viruses. AnMBRvirus infects the boot sector of floppy disks or theMaster Boot Record(MBR) of hard disks.

What is an MBR virus?

The infected code runs when the system isbootedfrom an infected disk. It also has a tendency to spread very fast since once loaded, it will infect other floppy disks when accessed in the infected computer.

They are a primitive type of coding that is seen rarely nowadays because of the different programming languages. However, they aren’t completely gone and can cause havoc when they manifest.

How does an MBR virus spread?

MBRviruses are most commonly spread using physical media such as an infected floppy disk or USB drive connected. It finds its way into the PC when the drive is accessed, and it will then modify or replace the existing boot code.

Next time you try to open your PC, the virus will be loaded and run immediately as part of themaster boot record. Most of the time, this result in you not being able tobootthe PC at all.

It can also cause the PC to lose CD-ROM support or causeMicrosoft Windowsto run in Compatibility Mode.
