What is the most expensive computer system infection in history?

The most pricey computer system virus in history is the Love Bug infection, which was released in 2000.  https://guayhk.com/?p=713 This infection caused an approximated $5.5 billion in damage worldwide, making it the most expensive infection ever. The Love Bug virus was a mass-mailing worm that infected over 45 million computer systems in simply a couple of days. The virus spread quickly by emailing itself to everybody in the victim's address book. As soon as a computer was infected, the infection would erase crucial files and spread itself to other computer systems.  https://insiderussia.today/?p=400 The Love Bug infection was eventually dropped in a team of antivirus scientists who created a vaccine that might protect computer systems from the infection.
