What are the Top 5 Most Dangerous Computer Viruses?
A computer virus is a software program that can copy itself and infect a computer without the user’s knowledge. A virus might corrupt or delete data on your computer, use your email program to spread itself to other computers, or even erase everything on your hard drive.
The five most dangerous computer viruses of all time are:
1. The Morris Worm
The Morris Worm was one of the first computer viruses to cause widespread damage. Released in 1988, it was designed to exploit vulnerabilities in the UNIX operating system. The worm was successful in infecting more than 6,000 computers, resulting in an estimated $10 million in damages.
2. The ILOVEYOU Virus
The ILOVEYOU virus was released in 2000 and quickly spread through email attachments. Once opened, the virus would automatically forward itself to everyone in the victim’s address book. The ILOVEYOU virus is estimated to have caused over $5.5 billion in damages.
3. The Melissa Virus
The Melissa virus was released in 1999 and, like the ILOVEYOU virus, spread through email attachments. Once opened, the virus would infect the victim’s computer and spread itself to everyone in their address book. The Melissa virus is estimated to have caused $80 million in damages.
4. The Code Red Worm
The Code Red worm was released in 2001 and quickly spread itself to millions of computers running Microsoft’s IIS web server software. The worm would then launch a denial of service attack against the whitehouse.gov website. The Code Red worm is estimated to have caused over $2 billion in damages.
5. The MyDoom Virus
The MyDoom virus was released in 2004 and is considered to be the fastest-spreading email virus of all time. The virus would spread itself through email attachments and, once opened, would allow the attacker to take control of the victim’s computer. The MyDoom virus is estimated to have caused over $10 billion in damages.
What are some steps people can take to protect their computer from viruses?
Most people know that they need to have some type of antivirus software installed on their computers to protect against viruses, but there are other steps that can be taken to further protect your computer. Below are some tips on how to protect your computer from viruses.
1) Keep your operating system and software up to date – One of the best ways to protect your computer against viruses is to make sure that your operating system and all software is up to date. Software developers release updates to patch security vulnerabilities that can be exploited by viruses. So, by keeping your software up to date, you are effectively patching any vulnerabilities that could be exploited.
2) Use a firewall – A firewall can help to protect your computer by blocking incoming traffic that could be malicious. Many routers come with a firewall built in, but you can also install firewall software on your computer.
3) Be cautious when opening email attachments – Email is one of the most common ways for viruses to spread. If you receive an email with an attachment from someone you don’t know, or even from someone you do know but wasn’t expecting an email with an attachment from them, be cautious before opening it. If you’re not expecting an attachment, it’s best to contact the person to confirm that they actually sent it before opening it.
4) Don’t click on links in emails from unknown senders – Another way that viruses can spread via email is by embedding links in the email that, when clicked, will download and install the virus on your computer. So, even if an email looks legitimate, if you don’t know the sender, it’s best to err on the side of caution and not click on any links in the email.
5) Be cautious when downloading files from the internet – Whether it’s downloading a program, music, or even just a picture, you should be cautious when downloading files from the internet. If you’re not sure if a file is safe, do a quick search online to see if there are any reports of it being malicious. It’s also a good idea to scan any files you download with your antivirus software before opening them.
6) Don’t give out personal information online – Be careful about what personal information you give out online. If a website is asking for information that you don’t feel comfortable giving, it’s probably best to just avoid the website altogether. In general, you should only give out personal information online if you’re sure that the website is legitimate and that the information will be used in a way that you’re comfortable with.
By following the tips above, you can help to protect your computer against viruses and other malware.
