The Melissa virus, also known as “I Love You” or “Mailissa,” is a computer worm that was discovered in March 1999. It was a type of malware that spread rapidly through email, infecting an estimated 1 million computers worldwide and causing widespread damage. In this article, we will delve into the history of the Melissa virus, its impact, and the lessons learned from this devastating cyber attack.
What is the Melissa Virus?
The Melissa virus was a Visual Basic Scripting (VBS) worm that was designed to spread through email. It was created by David L. Smith, a 30-year-old computer programmer from New Jersey, who released the virus on March 26, 1999. The virus was named after a stripper that Smith had met in Florida, and it was designed to spread rapidly through email, using a technique called “social engineering.”
How Did the Melissa Virus Spread?
The Melissa virus spread through email, using a technique called “social engineering.” The virus would send an email to the victim’s Microsoft Outlook contacts, with the subject line “I Love You” and an attachment called “LIST.DOC.” The email would appear to be from a friend or acquaintance, and the attachment would be a Word document that contained the virus.
When the victim opened the attachment, the virus would infect their computer, and then send emails to all of their Outlook contacts, using the same subject line and attachment. This created a snowball effect, with the virus spreading rapidly through email.
Technical Details of the Melissa Virus
The Melissa virus was a VBS worm that used a technique called “macro viruses” to infect computers. Macro viruses are a type of malware that uses macros, which are small programs that can be embedded in documents, to infect computers.
The Melissa virus used a macro virus to infect computers, and it was designed to spread through email. The virus would infect a computer, and then send emails to all of the victim’s Outlook contacts, using the same subject line and attachment.

What is the Melissa Virus?
The Melissa Virus is a computer worm that was first discovered in March 1999. It was a type of malware that spread through email attachments, specifically Microsoft Word documents. The virus was designed to replicate itself and spread to other computers, causing significant damage and disruption to computer systems worldwide.
The Melissa Virus was named after an exotic dancer in Florida, and it was created by David L. Smith, a computer programmer from New Jersey. The virus was designed to spread quickly and quietly, and it was able to infect thousands of computers before it was detected. The virus was particularly devastating because it was able to spread through email attachments, which were a common way for people to share files at the time.
How did the Melissa Virus spread?
The Melissa Virus spread through email attachments, specifically Microsoft Word documents. When a user opened an infected document, the virus would activate and begin to replicate itself. The virus would then send itself to the first 50 addresses in the user’s Microsoft Outlook address book, using the subject line “Important message from [username]”. The email would contain a message that said “Here is that document you asked for … don’t show anyone else ;-)”.
The virus was able to spread quickly because it was able to use the user’s own email account to send itself to other people. This made it difficult to track the source of the virus, and it allowed the virus to spread rapidly across the internet. The virus was also able to infect computers that were running Windows 95, Windows 98, and Windows NT, which were the most common operating systems at the time.
What were the effects of the Melissa Virus?
The Melissa Virus had significant effects on computer systems worldwide. It is estimated that the virus infected over 1 million computers, and it caused an estimated $1 billion in damages. The virus was particularly devastating to large corporations and government agencies, which had to shut down their email systems to prevent the spread of the virus.
The virus also had a significant impact on the way that people thought about computer security. It highlighted the importance of being cautious when opening email attachments, and it led to the development of new security measures to prevent the spread of malware. The virus also led to changes in the way that email was used, with many companies implementing new policies to prevent the spread of malware through email.
How was the Melissa Virus stopped?
The Melissa Virus was stopped through a combination of efforts by computer security experts and law enforcement agencies. The virus was first detected on March 26, 1999, and it was quickly identified as a type of malware. Computer security experts worked to develop a patch to fix the vulnerability that the virus was exploiting, and they also developed tools to remove the virus from infected computers.
