ANTIVIRUS SOFTWARE:

Full protection: Antivirus software from reputable third-party vendors often offers a wide range of features and advanced technologies, providing robust protection against various types of malwares.
Advanced threat detection: Many antivirus programs employ advanced detection techniques, such as behaviour-based analysis, machine learning, and investigative scanning, to identify new and emerging threats that may not have known signatures.
Customization and flexibility: Antivirus software allows users to customize settings, schedule scans, and configure the level of protection according to their specific needs and preferences.
Additional security features: Antivirus software often includes supplementary features like web protection, email scanning, firewall integration, vulnerability scanning, and parental controls, offering a comprehensive security suite in one package.
Constant updates: Antivirus software regularly updates its virus definitions and databases to keep up with the latest threats, ensuring effective protection against new malware variants.
Support and customer service: Reputable antivirus vendors typically offer customer support, providing assistance in case of any issues or queries related to the software.

Limitations

Apart from the advantages of the Windows Defender and Antivirus Software, there are some limitations and disadvantages to them, too. And they are as follows:

WINDOWS DEFENDER:

1. Basic feature set: While Windows Defender provides core protection against common threats, it may lack some advanced features found in dedicated third-party antivirus software. Users seeking additional functionalities or customization options may find Windows Defender to be limited.

2. Slower response to emerging threats: As Windows Defender is developed by Microsoft, it may have a slightly slower response time compared to dedicated antivirus vendors in terms of releasing updates and patches for newly discovered threats.

3. Less frequent updates: While Windows Defender receives automatic updates through Windows Update, the frequency of these updates may be less frequent compared to some third-party antivirus software that frequently release updates to address emerging threats.

4. Limited customer support: Windows Defender’s support options may be more limited compared to dedicated antivirus vendors, which often provide extensive customer support services.

5. Compatibility with older Windows versions: Some of the newer features and improvements of Windows Defender may not be available or fully supported on older versions of the Windows operating system, limiting its effectiveness for users who have not upgraded to the latest Windows version.

ANTIVIRUS SOFTWARE:

1. False positives: Antivirus software may occasionally flag valid files like any games files or programs as malware, resulting in false positive detections. This can disrupt normal operations and lead to unnecessary actions like quarantining or deleting harmless files.

2. Zero-day vulnerabilities: Antivirus software relies on regular updates to detect and protect against new malware variants. However, it may not be effective against zero-day vulnerabilities, which are newly discovered and exploited before antivirus vendors can release updates.

3. Resource usage: Some antivirus software can be resource-intensive, consuming significant CPU power, memory, and disk space. This can slow down system performance, especially on older or less powerful computers.

4. Incompatibility with other software: Certain antivirus programs may have compatibility issues with specific software applications or configurations, leading to conflicts or unstable behaviour.

5. Evolving malware techniques: Cybercriminals continually develop new techniques to evade antivirus detection, such as polymorphic malware, fileless malware, or encrypted payloads. Antivirus software may struggle to keep up with these evolving threats.

6. Limited protection against targeted attacks: Advanced targeted attacks, such as spear-phishing or advanced persistent threats (APTs), may bypass traditional antivirus defences as they rely on social engineering or sophisticated techniques that are not solely based on malware.
