Most dangerous computer virus in the world

It is estimated that over482,000 new malware samples were added to VirusTotal in the first quarter of 2018 alone. This is a 38% increase from the previous quarter and a staggering 522% increase from the first quarter of 2017. With such a large and ever-growing volume of malware, it can be difficult to determine which viruses are the most dangerous.

To help answer that question, we’ve compiled a list of the 10 most dangerous computer viruses of all time. These are the viruses that have caused the most damage, either in terms of financial losses or in terms of the number of people affected.

1. LoveHeart

LoveHeart is a virus that hit Taiwan in 2003 and caused an estimated $15 million in damage. The virus spread primarily through instant messages, tricking people into clicking on links that would install the virus. Once installed, the virus would send itself out to everyone in the victim’s address book.

2. ILOVEYOU

ILOVEYOU is a virus that hit computers in 2000 and caused an estimated $10 billion in damage. The virus spread primarily through email, with victims receiving an email with the subject line “I LOVE YOU” and an attachment.

3. MyDoom

MyDoom is a virus that hit computers in 2004 and caused an estimated $38.5 billion in damage. The virus spread primarily through email, with victims receiving an email with the subject line “hi” and an attachment. If the attachment was opened, the virus would install itself and give the attacker access to the victim’s computer. The attacker could then use the victim’s computer to send out spam emails or launch attacks on other computers.

4. Sasser

Sasser is a virus that hit computers in 2004 and caused an estimated $18.5 billion in damage. The virus spread primarily through computers that were vulnerable to a specific Windows flaw. Once the virus infected a computer, it would start scanning the internet for other vulnerable computers and infect them as well.

5. Crysis

Crysis is a virus that hit computers in 2007 and caused an estimated $1 billion in damage.

How have the most dangerous computer viruses in the world evolved over time?

The most dangerous computer viruses in the world have evolved over time to become more sophisticated and more difficult to detect and remove. The earliest viruses were relatively simple programs that replicated themselves and caused little or no damage to the affected computer. However, as viruses have become more sophisticated, they have been able to cause more damage, Steal sensitive information, and even take control of the affected computer.

One of the most famous and feared viruses of all time is the Melissa virus, which was first released in 1999. Melissa was a relatively simple virus that infected Microsoft Word documents and spread itself by emailing itself to people in the victim’s address book. However, despite its relatively simple design, Melissa was responsible for causing billions of dollars in damage and bringing down several major corporations’ email systems.

Since the release of Melissa, viruses have become much more sophisticated and dangerous. The ILOVEYOU virus, released in 2000, was far more destructive than Melissa, infecting not only Word documents but also Excel spreadsheets and PowerPoint presentations. ILOVEYOU also spread itself much more aggressively, emailing itself to everyone in the victim’s address book instead of just the first few contacts. As a result, ILOVEYOU was responsible for causing an estimated $5.5 billion in damage and infecting more than 50 million computers.

The Mydoom virus, released in 2004, was even more destructive than ILOVEYOU. Mydoom was aworm, meaning that it spread itself without the need for any user interaction. It also had the ability to take control of the affected computer and use it to launch attacks against other computers. Mydoom was responsible for causing an estimated $38 billion in damage and was, at the time, the fastest-spreading virus in history.

The most recent and dangerous virus is the WannaCry ransomware, which was released in 2017. WannaCry is a type of malware that encrypts the victim’s files and demands a ransom be paid in order to decrypt them. WannaCry was particularly dangerous because it exploitedd a vulnerability in Microsoft Windows that allowed it to spread quickly and easily. As a result, WannaCry was responsible for infecting more than 200,000 computers in 150 countries and causing an estimated $4 billion in damage.

As you can see, the most dangerous computer viruses in the world have evolved over time to become more sophisticated and more destructive. It is important to be aware of these evolving threats and to take steps to protect your computer and your data.
