What is the most dangerous computer virus and why?

The most dangerous computer virus is WannaCry. It is a ransomware virus that targets Windows systems. It was first discovered in May of 2017, and since then, it has infected over 230,000 computers in 150 countries. The virus encrypts files on the infected computer and demands a ransom be paid in order to decrypt the files. WannaCry has caused over $4 billion in damage so far.

The reason WannaCry is so dangerous is because it is easily spreadable and difficult to protect against. The virus exploits a vulnerability in Windows systems that allows it to spread quickly and easily. Once a computer is infected, the virus starts scanning for other vulnerable computers on the same network and infects them as well. The virus also spread quickly because many people were not aware of the vulnerability in Windows and did not have the proper security measures in place.

WannaCry is also difficult to protect against because it uses strong encryption. When the virus encrypts a file, it is very difficult to decrypt it without the ransom key. Even if you have a backup of the files, you will not be able to access them unless you pay the ransom. This has caused a lot of people to simply pay the ransom and hope that they will get their files back.

The best way to protect against WannaCry is to make sure that your computer is up to date with the latest security patches. You should also have a good antivirus program installed.

There are many dangerous computer viruses in the world, but some are more dangerous than others. The most dangerous computer virus is the WannaCry virus. This virus targets Microsoft Windows users and encrypts their files, making them inaccessible. The virus then demands a ransom from the victim in order to decrypt their files. This virus has caused millions of dollars in damages and has affected many businesses and organizations around the world.

What are the most common computer viruses?

The most common computer viruses are:

1. The ILOVEYOU virus

This is a type of Trojan horse virus that first appeared in 2000. It quickly spread around the world, causing billions of dollars in damage. The ILOVEYOU virus disguised itself as a love letter, which is why it was so successful in tricking people into opening it. Once opened, the virus would send itself to everyone in the victim’s address book and delete important files on their computer.

2. The Melissa virus

The Melissa virus was another Trojan horse virus that emerged in 1999. It was spread via email and would infect a computer when the user opened a certain email attachment. The virus would then replicate itself and send itself out to everyone in the victim’s address book. As with the ILOVEYOU virus, the Melissa virus caused billions of dollars in damage.

3. The Code Red virus

This is a type of worm virus that first appeared in 2001. It was notable for being the first virus to exploit a previously unknown security vulnerability in the Microsoft Windows operating system. The Code Red virus would spread itself by creating copies of itself on any computer that it infected. It would then launch a denial of service attack against the White House website.

4. The SQL Slammer virus

This virus emerged in 2003 and was notable for being one of the fastest spreading viruses of all time. It managed to infect over 75,000 computers within 10 minutes of first appearing. The SQL Slammer virus exploited a security vulnerability in Microsoft’s SQL Server software. It caused denial of service problems for many websites and Internet service providers.

5. The Sasser virus

The Sasser virus was another fast-spreading virus that first appeared in 2004. It was similar to the SQL Slammer virus in that it exploited a security vulnerability in Microsoft Windows. The Sasser virus caused infected computers to reboot repeatedly, which made them unusable.

These are just some of the most notable and damaging computer viruses of recent years. While there have been many other viruses that have caused damage, these five stand out as the most significant.

What is the most dangerous computer virus in the world?

The most dangerous computer virus in the world is the WannaCry virus. This virus encrypts all of the files on a victim’s computer and then demands a ransom in order to decrypt the files. The WannaCry virus has caused millions of dollars in damages and has affected organizations all over the world, including the NHS in the UK. This virus is particularly dangerous because it exploits a vulnerability in Windows that was previously unknown. This means that many computers are still vulnerable to this virus, even though a patch has been released by Microsoft.

How did the most dangerous computer virus get created?

The most dangerous computer virus in the world is the Conficker virus. This virus was first discovered in 2008, and it has been wreaking havoc ever since. The virus is particularly dangerous because it is so versatile. It can infect computers running Windows XP, Vista, 7, 8, and 10. It can also spread through networks, and it can even infect USB devices.

Conficker is a “worm” virus, which means that it is designed to spread itself. It does this by creating a network of infected computers, and then using that network to infect new computers. The virus is also designed to be difficult to remove, and it can disable security features on an infected computer.

The virus was first discovered in 2008, but it is believed to have been created in 2007. It is not clear who created the virus, but it is believed to be the work of a team of skilled programmers. The virus was likely created for financial gain, as it can be used to steal sensitive information or to take over computers for malicious purposes.

Conficker is not the only dangerous virus out there, but it is certainly the most dangerous. If you have any suspicion that your computer may be infected with Conficker, you should take action immediately. There are a number of free tools available that can help you remove the virus from your computer.
