First PC Virus: Brain Infiltrates Digital World
Two brothers from Lahore, Basit and Amjad Farooq Alvi, wrote the first virus for IBM-compatible personal computers in 1986. They embedded their names, address, and phone numbers in the code because their intent was not malicious but retaliatory: local customers were pirating their medical software, and the virus was designed to slow down unauthorized copies by infecting the boot sector of floppy disks. The virus spread far beyond Pakistan, traveling on shared diskettes to universities and offices across the globe. When recipients called the number in the code, the brothers offered to remove it. The incident revealed that the emerging personal computer ecosystem had zero defenses against self-replicating software. Within three years, the antivirus industry emerged as a billion-dollar market, and the concept of computer security became inseparable from digital life.
