This coded boot virus is named by a string contained in its body. Text in the string contains a grammatically incorrect English piece of text:
This virus is from Mexico, I have 15 years old.
When a computer attempts to boot from an infected diskette the virus attacks the hard disc MBR, occupies the interrupt INT 13h and tries to infect the boot sector of any diskette in the drive that is not write protected. It checks the system date and on April 7 it overwrites the disk by a Spanish text string.
