Hello! It seems like your network has been affected by the Port 138-NETBIOS and Port 139-NETBIOS-SN trojans. These ports are commonly used by malware for malicious activities. Here are some steps you can take to address the issue:

1. Identify the Infected Machines: Use a network scanning tool or antivirus software to identify which machines on your network are infected with the trojans. Once you have identified the affected devices, isolate them from the network to prevent further spread of the malware.

2. Remove the Malware: Run a full system scan on the infected machines using reputable antivirus software to detect and remove the trojans. Make sure your antivirus definitions are up to date to effectively detect the malware.

3. Update Software and Operating Systems: Ensure that all devices on your network have the latest software updates and security patches installed. Vulnerabilities in outdated software can be exploited by malware to infect your network.

4. Change Default Passwords: Make sure that all devices on your network have strong, unique passwords to prevent unauthorized access. Change default passwords on routers, servers, and other network devices.

5. Disable Unused Services: If you are not using NetBIOS services, consider disabling them on your network devices to prevent potential vulnerabilities.

6. Monitor Network Traffic: Set up network monitoring tools to detect any suspicious activity on your network. Monitor traffic on ports 138 and 139 to identify potential threats.

7. Educate Users: Educate your employees or users about the importance of cybersecurity practices such as avoiding suspicious links, not downloading attachments from unknown sources, and being cautious while browsing the internet.

8. Backup Data: Regularly backup your important data to an external storage device or cloud service. In case of a malware attack or data loss, you can restore your data from backups.

By following these steps, you can help secure your network and prevent further infections from Port 138-NETBIOS and Port 139-NETBIOS-SN trojans. If you need further assistance, feel free to ask!
