Business Intelligence Lowdown compiled a nice piece of linkbait, they listed the top 10 of most hilarious viruses, trojans and worms.
1. The "Very Funny" or "I Love You" Virus: This one hit the Internet in the year 2000 and corrupted image and music files on user systems. Identified initially by the words "I love you" or "Joke: Very Funny" in the subject line of an email, the virus was later passed around as newer, more malicious versions that overwrote important files needed to boot the computer. These masqueraded as Mother's Day messages or Lithuanian flirting techniques – some email came with the tag "Let's meet for a cup of coffee," in Lithuanian, of course. Bolder versions took advantage of the scare created by their predecessors, and pretended to be representatives from anti-virus software providers. They asked users to execute the attachment to eradicate all viruses from their computers!
