Rotceh
Description Rotceh
It is a very dangerous memory resident boot virus. It hooks INT 13h and writes itself to the boot sectors of floppy disks and to the MBR of the hard drive. While infecting a floppy disk the virus writes the original boot sector to the 7th sector of the disk. This sector is one of FAT sectors, and as a result the virus corrupts FAT on the floppy disks. The virus checks the system date and in November it tries to erase the disk sectors, decrypt and display the message, but it has a bug and in any case returns from this routine without any harm. The message is:
