What is the most expensive bug in history?

The most costly virus in history is the Love Bug infection, which was launched in 2000. This virus caused an estimated $5.5 billion in damage worldwide, making it the most costly infection ever.  A bug is a sort of malicious code or program that, when carried out, reproduces by putting itself right into other computer programs, information files, or the boot field of the disk drive. Therefore, computer viruses can spread throughout a network of computer systems and also create serious damage.https://malwarezero.org/different-types-of-viruses-for-computers-a-beginners-guide/ The Love Bug virus was a mass-mailing worm that contaminated over 45 million computers in simply a few days. The infection spread quickly by emailing itself to everyone in the victim's address book. Once a computer system was infected, the virus would delete important files and spread itself to other computers. The Love Bug virus was eventually stopped by a team of anti-virus scientists who created a vaccine that could safeguard computers from the virus.
