,
There are many different types of computer viruses out there, and new ones are always being created. Some are more dangerous than others, and can cause serious harm to your computer. Here are some of the most dangerous computer viruses and what they can do:
1. The ILOVEYOU virus is a destructive virus that was first released in 2000. It spread quickly, affecting millions of computers worldwide. The virus would send itself out to everyone in your address book, and then delete important files on your computer. It would also display a fake love letter on your screen, tricking you into thinking it was from someone you knew.
2. The Code Red virus was another destructive virus that was released in 2001. It affected servers running Microsoft’s IIS web server software. The virus would overload the server, causing it to crash. It could also give the attacker control over the server.
3. The Sasser virus was released in 2004 and spread quickly, affecting millions of computers. It was a worm, meaning it would spread itself without any user interaction. The virus would cause computers to crash and then restart on their own.
4. The MyDoom virus was released in 2004 and is considered to be the fastest-spreading virus of all time. It would send itself out to everyone in your address book and then allow remote access to your computer. It would also display annoying pop-ups on your screen.
5. The Storm Worm was released in 2007 and quickly spread to computers all over the world. It was a worm that used social engineering to trick people into opening infected email attachments. The virus would then give the attacker control over the infected computer.
These are just some of the most dangerous computer viruses out there. There are many others that can cause serious harm to your computer. Be sure to install antivirus software and keep it up to date to help protect your computer from these threats.
What are the most common computer viruses?
of 2018
There are many different types of computer viruses, and new ones are created all the time. Some viruses are more common than others, and some are more dangerous. The most common computer viruses include the following:
1. The trojan horse: This type of virus is hidden within another program or file, and is often used to steal personal information or wreak havoc on a computer.
2. The worm: This type of virus is designed to spread itself by replicating itself and sending itself to other computers. Worms can cause massive damage by taking down networks or infecting a large number of computers.
3. The ransomware: This type of virus encrypts files on a computer and demands a ransom be paid in order to decrypt the files. This can be particularly devastating for businesses or individuals who have important data that is inaccessible.
4. The adware: This type of virus displays unwanted advertisements on a computer. Adware can be annoying and intrusive, but is generally not considered to be as serious as other types of viruses.
5. The spyware: This type of virus is designed to collect personal information from a computer without the user’s knowledge. Spyware can be used to steal passwords, credit card information, and other sensitive data.
The most dangerous computer virus of 2018 is the WannaCry ransomware. This virus infected computers all over the world, and demanded that users pay a ransom in order to access their files. The WannaCry virus caused billions of dollars in damage, and highlighted the importance of having good cyber security.
How can I protect my computer from the most dangerous computer virus?
There is no foolproof way to protect your computer from viruses, but there are some steps you can take to minimize the risk. Keep your operating system and software up to date. This is important because developers often release updates that include security patches for newly discovered vulnerabilities. Use a reputable antivirus program and supplement it with a firewall. Be careful what you download and be sure to scan anything you are unsure of. Be cautious when opening email attachments, even if they appear to be from a trusted sender. When possible, back up your data. This way, if your computer is infected, you can restore your files from a backup.

What is the most dangerous computer virus in the world?
is “____”
There is no definitive answer to this question as it largely depends on the individual computer user’s level of vulnerability. However, some of the most dangerous computer viruses in the world include the following:
The Conficker virus, first discovered in 2008, is considered one of the most dangerous computer viruses in existence. The virus is particularly dangerous because it is able to spread quickly and infect a large number of computers, wreaking havoc on networks and individual computers alike.
The ILOVEYOU virus is another dangerous virus that first emerged in 2000. The virus spread quickly via email, with unsuspecting users opening attachments that unleashed the virus. ILOVEYOU was particularly destructive, causing an estimated $5.5 billion in damages worldwide.
The Melissa virus is yet another destructive virus that emerged in the early 2000s. Like ILOVEYOU, Melissa spread via email attachments, causing significant damage to corporate networks. The virus was created by David L. Smith and named after a topless dancer in Florida.
These are just a few of the most dangerous computer viruses in the world. While there is no surefire way to protect your computer from these and other threats, installing and updating antivirus software can help to reduce the risk.
