Scan your computer regularly to identify and eliminate potential threats.

5. Limit Administrator Privileges

Avoid using administrator accounts for everyday tasks.
Create separate user accounts with limited privileges to minimize the impact of compromised accounts.
Use administrator privileges only when necessary and revoke them as soon as possible.

6. Be Cautious of Phishing and Social Engineering Attacks

Phishing emails or messages can look legitimate but are designed to trick you into revealing sensitive information.
Verify the sender’s identity before clicking on links or providing personal data.
Use caution when interacting with unsolicited messages or requests for personal information.

7. Use a Virtual Private Network (VPN)

A VPN encrypts your internet traffic, making it harder for attackers to intercept your data.
It is especially important when using public Wi-Fi networks.
Choose a reputable VPN provider that offers strong encryption and a privacy policy that aligns with your needs.

8. Back Up Your Data Regularly

Regularly back up your important data to an external hard drive or cloud storage solution.
This ensures that you have a copy of your data in case of a system failure, ransomware attack, or data loss.
Consider using an automated backup solution to ensure regular and consistent backups.

9. Use a Web Application Firewall (WAF)

A WAF monitors and filters incoming web traffic to identify and block malicious requests.
It can help prevent attacks such as SQL injection, cross-site scripting, and distributed denial of service (DDoS) attacks.

10. Implement Firewall and Network Security Controls

Configure your firewall to block unauthorized access to your computer.
Use a network security solution, such as a network intrusion detection/prevention system (IDS/IPS), to detect and respond to potential threats.
Monitor network traffic for suspicious activity and take appropriate countermeasures.
