The most dangerous computer virus ever created is called “ILOVEYOU”. It was created in 2000 and spread quickly, causing billions of dollars in damage. The virus was difficult to detect and remove, and it continues to cause problems today. “ILOVEYOU” is a particularly damaging virus because it spread quickly and easily, and it was difficult to remove. The virus caused billions of dollars in damage, and it continues to cause problems today earning its spot as the most dangerous computer virus of all time.

This famous computer virus was a computer worm that spread rapidly through email attachments in May 2000. The worm was written in the programming language VBScript and was initially spread by email attachments with the subject line “I Love You” and the message body “Here is a love letter for you”. The attachment would be an executable file with a “.vbs” extension. When executed, the worm would search all files with a “.vbs” extension and prepend the worm’s code to the start of the file. It would also send itself to all email addresses it found in the victim’s email client.

The worm was able to spread quickly because it took advantage of a vulnerability in Microsoft Outlook and Outlook Express. The worm would send itself in an email with the following header:

Content-Type: text/html
Content-Transfer-Encoding: 7bit

The email would also have a bogus sender address, which would often be an email address known to the victim. This would trick the victim into thinking the email was safe to open.

Once the email was opened, the worm would execute and start replicating itself. The worm would also display the following message:

“I Love You”

The message would often be accompanied by music, which would play in the background.

The ILOVEYOU virus was first discovered on May 4, 2000, by a computer user in the Philippines. The virus quickly spread around the world, causing an estimated $5.5 billion in damage earning its title as most dangerous virus in the world. The worm was eventually stopped by a software patch released by Microsoft.
