What is the most expensive computer virus in history?

The most expensive computer virus in history is the Love Bug infection, which was released in 2000. This virus triggered an estimated $5.5 billion in damage worldwide, making it the most expensive infection ever. The Love Bug virus was a mass-mailing worm that contaminated over 45 million computers in just a few days. The infection spread rapidly by emailing itself to everybody in the victim's address book. When a computer system was contaminated, the virus would delete crucial files and spread itself to other computers. The Love Bug infection was eventually dropped in a group of anti-virus scientists who developed a vaccine that might secure computers from the virus. This Site
