What is the most costly trojan horse in history?

The most pricey computer system virus in history is the Love Bug infection, which was released in 2000. This virus triggered an approximated $5.5 billion in damage worldwide, making it the most expensive virus ever. The Love Bug virus was a mass-mailing worm that infected over 45 million computer systems in simply a few days. The infection spread quickly by emailing itself to everyone in the victim's address book. When a computer system was infected, the infection would erase essential files and spread itself to other computer systems. The Love Bug infection was ultimately dropped in a group of antivirus scientists who developed a vaccine that could safeguard computer systems from the infection. https://romanquarterconsultation.co.uk/?p=267
