How does most dangerous virus computer spread?
The most common way for a computer virus to spread is by email. When you open an email from someone you don’t know, or even from someone you do know, you could be opening your computer up to a virus. The virus will attach itself to the email and then be sent to everyone in your address book. That’s why it’s important to be careful about which emails you open.
Another way that viruses spread is by downloading files from the Internet. If you download a file that has a virus attached to it, the virus will be downloaded along with the file. This is why it’s important to be careful about what you download, and to make sure that you have a good antivirus program installed on your computer.
If you’re not careful, a virus can spread quickly and cause a lot of damage to your computer. That’s why it’s important to be careful about what you do on your computer, and to make sure that you have a good antivirus program installed..Full Article
What is the most dangerous virus computer?
Viruses are bits of code that can replicate themselves and cause damage to files or systems. While there are many different types of computer viruses, some are more dangerous than others. Here are four of the most dangerous viruses that have caused major havoc on computers around the world.
1. ILOVEYOU
This virus, also known as Love Letter or Lovebug, first surfaced in the Philippines in 2000. It quickly spread around the world, infecting millions of computers and causing billions of dollars in damage. The ILOVEYOU virus worked by emailing itself to everyone in the victim’s address book. The email had the subject line “ILOVEYOU” and the message “kindly check the attached LOVELETTER coming from me.” The attachment was actually a virus that would overwrite important files on the victim’s computer. It would also email itself to everyone in the victim’s address book, causing the virus to spread quickly.
2. Code Red
Code Red was a worm that infected computers running Microsoft’s IIS web server software. The worm first surfaced in July 2001 and quickly spread, infecting hundreds of thousands of computers. The damage caused by Code Red was estimated to be around $2 billion. The worm worked by taking advantage of a vulnerability in IIS and creating a buffer overflow. This allowed the worm to execute code on the server, which then allowed it to spread to other computers.
3. Melissa
This virus, named after a topless dancer in Florida, first surfaced in March 1999. Like the ILOVEYOU virus, it spread quickly by emailing itself to everyone in the victim’s address book. The email had the subject line “Here is that document you asked for…,” and the message “Don’t show this to anybody else.” The attachment was a virus that would overwrite important files on the victim’s computer. Melissa caused around $80 million in damage and resulted in the arrest of its creator, David L. Smith.
4. SQL Slammer
SQL Slammer was a computer worm that took advantage of a vulnerability in Microsoft’s SQL Server software. The worm was first discovered in January 2003 and quickly spread, causing billions of dollars in damage. The worm worked by flooding computers with random data, which caused them to crash. This caused widespread disruption, as many websites and email servers were taken offline.
