Each antivirus software has its own set of security features, such as firewall protection, web filtering, email scanning, and more. By combining these features, you create a multi-faceted defense system that can safeguard your system from various attack vectors.

For example, while Windows Defender may excel at detecting and removing malware, another antivirus program might have a more robust firewall feature. By using both programs, you can benefit from Windows Defender's malware detection capabilities and the advanced firewall protection provided by the other program. This synergy creates a comprehensive security solution that covers multiple angles of attack.

It is important to ensure that the antivirus programs you choose are compatible with each other and do not conflict in terms of functionality. Some antivirus software offers compatibility modes explicitly designed to work alongside Windows Defender, ensuring smooth operation and optimal protection.

4. Flexibility and Customization

Running Windows Defender with another antivirus program gives you flexibility and customization options to suit your specific security needs. Not all antivirus programs are created equal, and their strengths may vary based on different factors. By running multiple antivirus software, you can choose the best features and capabilities of each program to create a tailored security solution.

You can select one antivirus program as the primary solution for malware scanning and detection, while another program handles other security tasks, such as firewall protection or web filtering. This allows you to optimize your security setup and tailor it according to your preferences and requirements.

However, it is important to strike a balance and not overload your system with too many antivirus programs, as it may lead to diminished performance and potential conflicts. Select a limited number of antivirus software that complement each other well and meet your security needs without overwhelming your system.

In conclusion, running Windows Defender with other antivirus programs can provide enhanced malware detection, real-time protection, additional security layers, flexibility, and customization.
