How do computer viruses work?
Viruses can be spread in a number of ways, including:
- Email attachments
- Downloaded files
- Plugging in an infected USB drive
- Visiting an infected website
Once a virus is on your computer, it can start to replicate itself and spread to other files on your computer. It can also steal your data, such as your passwords or credit card numbers. In some cases, viruses can even take control of your computer and make it do things you don't want it to do.
The top computer viruses in history:
The ILOVEYOU virus: This virus was spread through email attachments and caused billions of dollars in damage in 2000.
The Code Red virus: This virus exploited a vulnerability in Microsoft's IIS web server and infected millions of computers in 2001.
The Nimda virus: This virus was also spread through email attachments and was even more destructive than ILOVEYOU.
The Slammer virus: This virus was a worm that spread very quickly through network vulnerabilities and caused widespread outages in 2003.
The Conficker virus: This virus was able to spread through a variety of methods, including network shares, USB drives, and even infected websites. It infected millions of computers in 2008.
The WannaCry virus: This ransomware virus spread through a vulnerability in Windows and encrypted files on infected computers, demanding a ransom payment to decrypt them. It infected over 200,000 computers in 2017.
These are just a few of the many computer viruses that have caused damage in the past. By being aware of these threats and taking steps to protect your computer, you can help to keep yourself safe from harm.
