The Love Letter computer virus, aka the “ILOVEYOU” bug, spreads to personal computers running Windows around the world in just six hours. Spreading through e-mail, the virus entices victims to open the message with the subject of “ILOVEYOU”. About 2.5 to 3 million PCs will become infected. The cost of system downtime is later estimated at $8.7 billion. It is thought to be the fastest-moving and most widespread virus in history.
