When the brothers created the virus, they were running a computer store in Lahore, Pakistan. They noticed that their customers were circulating illegal copies of software they’d written. So, they thought of a unique way of teaching their customers a lesson. They created the Brain virus.

The brothers stressed in interviews that they created the virus only for the illegal copies of the software. They put their names, phone numbers, and their shop’s address in the virus code. Basit and Amjad never thought of the virus growing into a global-sized monster. Its power was beyond their capacities to control it.

They realized how widespread their virus had become when they heard the angry voices of people from the UK and the US calling their store with demands for the brothers to disinfect their machines. The brothers claim that the virus was intended to be mostly harmless. It was simply displaying a copyright message about the pirated software. It was also changing the name of the floppy drive. However, many people reported that the virus has wiped data or caused their drives to become slow and unresponsive.

There was never any legal action, but the media response was explosive, and people from all around the world blocked the brothers’ phone with furious calls. However, despite all the fuss their virus caused in the world, Brain was never bad for the brothers’ business. Their company, Brain Net, is now the largest Internet service provider in Pakistan. While they maintain that they never meant to hurt anyone, they have nevertheless embraced Brain as a device that exposed the global nature of piracy.

In 2011, 25 years after Brain was released, Mikko Hyppönen of F-Secure traveled to Pakistan to interview Amjad.
