The World's Worst Computer Virus: The I Love You Virus (Demonstration)

This is a demonstration of the I Love You Virus (known mostly as “ILOVEYOU”), which was recognized by the Guiness Book of World Records as the worst computer virus of all time, causing more damage than anything like it before.

May 5, 2000 was just a very average day for the very average business supervisor. Though in just a couple of hours, it would quickly turn into a day of utter chaos and turmoil. Nearly every install of brand-new computer software damaged beyond repair, over 13,000 pieces of malware detected in just one office building, and soon, over $20 billion in damage seen all across the world. What happened?

These catastrophic events were the work of a new computer worm that was circulating the internet: “ILOVEYOU.”

Quite an ironic name, but it was derived from the fact that the worm would disguise itself as a love letter coming from a secret admirer. Lo and behold, the virus caused destroyed more computers than any of its predecessors. What exactly allowed it to cause this much damage, and how did it work?

The new computer worm was circulating the world wide web. Disguised as a love letter, the ILOVEYOU virus infected millions of computers around the world, causing collectively $20 billion in damage. ILOVEYOU has since been declared one of the most catastrophic computer viruses ever developed. And for the deaf people, I HAVE CLOSED CAPTIONS!!!

    I remember when this hit. It mainly just showed how easy it is to sucker people on a computer.
    What’s even weirder is that while computers are more prevalent now most people still don’t understand them.
    The most important thing to know about any virus: you have to intentionally run it. Which means you have to be pretty ignorant to get a computer virus.

    Now, yes there are some types of viruses that you could get by accident (an embed in an html script that lies to the user for example getting them to do something they don’t even know they’re doing), but this is super rare and these days highly unlikely to happen- still possible but unlikely.

    Just pay attention to what you click on I guess.
    What you should be more worried about now-a-days is being watched/listened to by governments and corporations. The way people unwittingly give away their information now is much scarier than a computer virus.

    I have seen such an interesting overwrite operation on an USB drive i used while printing in a printing center. The idea was for the assistant to just upload my file to their PC, but after sticking the same USB on my laptop, all my files were mysteriously converted to .exe files (well, not .vbs, but still unusable). It wasn’t a big drama and didn’t break my own computer, but nevertheless a nuisance…

  6. Tailspin80 on December 29, 2021 at 2:04 am

    Microsoft were being a bit gullible, allowing executable / vbs files to be emailed, then run from Outlook, without at any point warning the user or blocking the process. Of course, later on they intervened (with trust settings in Office, Windows Defender etc) to prevent all but the dumbest users being caught out, but why didn’t the developers see this one coming before it actually hit them?

    Imagine those who actually sent love letters titled I love you, right as this whole fiasco began. Those mfs never confessed to another soul.

    long ago in late 90s, i got infected with a love letter virus but it only affected all my JPEG files. The rest was intact. How I got it? It was sent to my email, which back then outlook express was integrated in windows’ software directly in the computer. I didnt even see the email. It automatically infected my computer once I opened my outlook express program.

  37. Jayrob thorn on December 29, 2021 at 2:45 am

    Should be an incentive for people to get out in the real world and make real friends and
    explore the world and take exercise like we used to, oh wait, the pandemic put paid to that now.

  38. samedoX on December 29, 2021 at 2:48 am
