Today in 2000, the ILOVEYOU computer bug began spreading from the Phillipines. Sent through e-mails and disguised as a file called "LOVE-LETTER-FOR-YOU," it infected around 3 million PCs in under 6 hours. It is considered the quickest and widest spreading computer virus in history. Once downloaded, the virus overwrote any files on the computer with certain common file extensions and replaced them with more copies of itself, eventually making the computer impossible to boot up. That's a good reminder to NEVER OPEN ANY E-MAILS OR FILE ATTACHMENTS without being sure they came from someone you trust.   Image Credit: Motherboard | VICE
