Use Strong and Unique Passwords
Creating strong and unique passwords is the first line of defense in computer security. Avoid using common or easily guessable passwords. Instead, follow these guidelines:
- Use a combination of uppercase and lowercase letters, numbers, and symbols.
- Make your passwords at least 12 characters long.
- Avoid using personal information or common dictionary words.
- Consider using a reputable password manager to generate and store your passwords securely.
Keep Your Operating System and Software Updated
Regularly updating your operating system and software is crucial for maintaining a secure computer. Updates often include security patches that address vulnerabilities. Follow these steps:
- Enable automatic updates for your operating system.
- Keep your software, including web browsers and plugins, up to date.
- Regularly check for updates manually if automatic updates are not enabled.
Install and Update Antivirus Software
Antivirus software plays a vital role in detecting and preventing malware infections. Here’s what you should do:
