What are Computer Viruses?

Types of Computer Viruses

  2. Keep Software Up to Date - Ensure that all software on your computer, including operating systems and applications, is up to date. This helps to close any security vulnerabilities that could be exploited by viruses.

  3. Be Cautious Online - Be careful when downloading files or clicking on links online, particularly from unknown sources.

  4. Use Strong Passwords - Use strong and unique passwords for all accounts and change them regularly.
