• ILOVEYOU is considered one of the most virulent computer virus ever created. It

managed to wreak havoc (带来巨大破坏) on computer systems all over the world

with around $10 billion worth of damages. 10% of the world’s computers were

believed to have been infected. It was so bad that governments and large

corporations took their mailing system offline to prevent infection.

• The virus was created by two Filipino programmers, Reonel Ramones and Onel de

Guzman. What it did was use social engineering to get people to click on the

attachment; in this case, a love confession. The attachment was actually a script

that poses as a TXT file, due to Windows at the time hiding the actual extension (扩

展名) of the file.

• Once clicked, it will send itself to everyone in the user’s mailing list and proceed to

overwrite files with itself, making the computer unbootable (无法启动). The two

were never charged, as there were no laws about malware. This led to the

enactment of the E-Commerce Law to address (解决) the problem.

DeadliestComputer Virus of All Time
