Anti-CNTE is a boot virus that infects the boot sector of floppy disks and hard disks and the Partition Table.
Anti-CNTE is considered a dangerous virus, as after infecting the computer, it counts the number of times the computer is booted. When the computer has been booted 300 times, Anti-CNTE displays a message on screen and overwrites sectors of the hard disk chosen at random. It will be impossible to recover the information contained in these sectors.
Anti-CNTE infects the hard disk of a computer when the computer is booted with a floppy disk infected by the virus. Then, all disks used in the computer will also be infected and the affected computer will have problems starting up.
Computers infected by Anti-CNTE have problems starting up and work more slowly than usual.
Sometimes, Anti-CNTE is easy to identify as it displays a black screen with a message and deletes some sectors of the hard disk, resulting in the loss of information:
This screen is displayed when the computer has been booted 300 times since it was infected.
