Cruel is a boot virus that infects the boot sector of floppy and hard disks.
Cruel infects the hard disk when the computer is booted from an infected floppy disk. From then on, all the floppy disks used on the computer will be infected and it will have problems starting up.
Cruel can be considered a dangerous virus, as:
- Sometimes, it corrupts the information of the boot sector preventing the computer from starting up from the infected disk. In this case, it is impossible to use the computer.
- Sometimes it deletes the information contained in the CMOS memory.
Sometimes, computers infected by Cruel will not start.
