What is the most costly virus in history?

The most costly computer system virus in history is the Love Bug infection, which was launched in 2000. 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 computers in simply a few days. The virus spread rapidly by emailing itself to everyone in the victim's address book. As soon as a computer system was infected, the virus would erase crucial files and spread itself to other computer systems. The Love Bug virus was eventually come by a group of antivirus researchers who developed a vaccine that might protect computer systems from the virus. https://islamhood.org/?p=634
