Avast, a well-known name in cybersecurity, offers a range of tools to protect your digital life. Among these, the Wi-Fi Inspector, often part of Avast’s Smart Scan, plays a crucial role in identifying security vulnerabilities within your network. This feature scans your router, computers, and other connected devices, flagging potential weaknesses as vulnerability IDs. Understanding and addressing these IDs is vital for maintaining a secure and robust home or office network. This article will guide you through understanding and fixing vulnerability IDs detected by Avast’s network scan.
Understanding Vulnerability IDs in Avast
When Avast performs a network scan, it’s essentially checking for common security loopholes that could be exploited by cyber threats. These loopholes are identified and categorized, often presented as vulnerability IDs. These IDs aren’t just random alerts; they are indicators of specific weaknesses in your network setup. The Wi-Fi Inspector tool within Avast 2019 and later versions is designed to pinpoint these issues, as highlighted in Avast’s own product announcements which emphasized enhanced network security features.

These vulnerabilities can range from weak router passwords to outdated firmware, or even open ports that could be exploited by malicious actors. Avast’s scan provides a user-friendly way to identify these often-overlooked security flaws in your connected environment. Think of it as a health check for your network, revealing areas that need immediate attention to prevent potential security breaches.
Steps to Fix Vulnerability IDs Identified by Avast
Once Avast’s scan, particularly the Smart Scan which incorporates the Wi-Fi Inspector, flags vulnerability IDs, it’s crucial to take action. Here’s a step-by-step guide to address these issues:
Step 1: Run an Avast Smart Scan
If you haven’t already, initiate a Smart Scan in your Avast security software. This comprehensive scan includes the Wi-Fi Inspector, which will analyze your network for vulnerabilities. Ensure your Avast software is up to date to leverage the latest vulnerability definitions and scanning capabilities. As mentioned in the release notes for Avast 2019, the Smart Scan feature was optimized for speed and efficiency, allowing for quicker identification of network issues.
Step 2: Access and Review Wi-Fi Inspector Results
After the Smart Scan, navigate to the Wi-Fi Inspector section to view the detailed results. Avast typically presents these findings in a clear, categorized manner. Look for sections highlighting “Vulnerabilities” or “Security Issues.” Each listed item will correspond to a vulnerability ID, often accompanied by a description of the issue and its potential impact. Pay close attention to the severity level assigned to each vulnerability.
Step 3: Understand and Act on Avast’s Recommendations
For each vulnerability ID, Avast usually provides recommendations on how to fix it. These recommendations are tailored to the specific issue detected. Common recommendations include:
- Changing Router Password: If Avast flags a weak router password, it’s crucial to update it to a strong, unique password. This is a primary defense against unauthorized network access.
- Updating Router Firmware: Outdated router firmware is a significant security risk. Avast may recommend updating your router’s firmware to the latest version provided by the manufacturer. Firmware updates often patch known vulnerabilities.
- Disabling WPS (Wi-Fi Protected Setup): WPS, while intended for easy connection, can be vulnerable to brute-force attacks. Disabling WPS and using a strong password is often recommended.
- Closing Open Ports: Avast might identify open ports that are potential entry points for attackers. Depending on the port and its necessity, you may need to close it or ensure it’s properly secured. This often involves router configuration.
Follow Avast’s guidance for each vulnerability ID. They are designed to be user-friendly and provide actionable steps.
Step 4: Implement Fixes Through Router and Device Settings
Most network vulnerability fixes involve adjustments to your router settings. Access your router’s administration interface, typically through a web browser by entering your router’s IP address (often 192.168.1.1 or 192.168.0.1). Use your router’s username and password (default credentials are often found on the router itself or in its manual – remember to change these if they are still default!).
Within the router interface, you can:
- Change the Wi-Fi password (usually under “Wireless” or “Wi-Fi Settings”).
- Update firmware (often under “Administration” or “System”).
- Disable WPS (usually under “Wireless” or “WPS Settings”).
- Manage port forwarding and firewall settings (under “Firewall” or “Security”).
For device-specific vulnerabilities, such as outdated software on a computer, follow Avast’s recommendations to update the software or operating system on the identified device.
Step 5: Re-run Avast Scan to Verify Fixes
After implementing the recommended fixes, run another Avast Smart Scan, including the Wi-Fi Inspector, to confirm that the vulnerability IDs have been resolved. A successful scan should show these previously flagged vulnerabilities as resolved, indicating a more secure network environment.
Maintaining Network Security and Preventing Future Vulnerabilities
Fixing vulnerability IDs is a proactive step, but maintaining network security is an ongoing process. Here are some best practices:
- Regular Avast Scans: Schedule regular Avast Smart Scans to continuously monitor your network for new vulnerabilities.
- Keep Software Updated: Ensure all devices on your network, including computers, smartphones, and smart devices, have the latest software updates and security patches.
- Strong Passwords: Use strong, unique passwords for your Wi-Fi network and router administration.
- Router Firmware Updates: Regularly check for and install router firmware updates from the manufacturer.
- Network Monitoring: Familiarize yourself with your router’s security features and consider enabling network monitoring or intrusion detection if available.
By understanding vulnerability IDs identified by Avast’s network scan and taking prompt action to fix them, you significantly enhance your network’s security posture. Regularly maintaining these security practices will help protect your network and devices from evolving cyber threats.
