Educating the end user on best practices for security is the next step that the technician should take after successfully removing malicious software from an infected computer. Educating the end user on best practices for security is an important part of preventing future infections and mitigating risks. The technician should explain to the end user how to avoid common sources of malware, such as phishing emails, malicious websites, or removable media. The technician should also advise the end user to use strong passwords, update software regularly, enable antivirus and firewall protection, and backup data frequently. Educating the end user on best practices for security can help the end user become more aware and responsible for their own security and reduce the likelihood of recurrence of malware infections. Quarantining the host in the antivirus system, investigating how the system was infected with malware, and creating a system restore point are not the next steps that the technician should take after successfully removing malicious software from an infected computer. Quarantining the host in the antivirus system is a step that the technician should take before removing malicious software from an infected computer. Quarantining the host in the antivirus system means isolating the infected computer from the network or other devices to prevent the spread of malware.
Investigating how the system was infected with malware is a step that the technician should take during or after removing malicious software from an infected computer. Investigating how the system was infected with malware means identifying the source, type, and impact of malware on the system and documenting the findings and actions taken. Creating a system restore point is a step that the technician should take before removing malicious software from an infected computer. Creating a system restore point means saving a snapshot of the system's configuration and settings at a certain point in time, which can be used to restore the system in case of failure or corruption.

Using disk-wiping software is the most secure method for removing information from past users' hard drives in order to reuse the hard drives. Disk-wiping software can help to ensure that all data on the hard drive is completely erased and cannot be recovered.

Windows 10 Enterprise is an edition of Windows 10 that is designed for large organizations that need advanced security and management features. Windows 10 Enterprise can be activated using different methods, such as Multiple Activation Key (MAK), Active Directory-based Activation (ADBA), or Key Management Service (KMS)1. KMS is a method of activation that uses a local server to activate multiple devices on a network. KMS activations are valid for 180 days and need to be renewed periodically by connecting to the KMS server2. If a device does not renew its activation within 180 days, it will enter a grace period of 30 days, after which it will display a warning message and lose some functionality until it is reactivated3. The other editions of Windows 10 do not require reactivation every 180 days. Windows 10 Pro for Workstation is an edition of Windows 10 that is designed for high-performance devices that need advanced features such as ReFS file system, persistent memory, and faster file sharing. Windows 10 Pro for Workstation can be activated using a digital license or a product key. Windows 10 Home is an edition of Windows 10 that is designed for personal or home use. Windows 10 Home can be activated using a digital license or a product key. Windows
10 Pro is an edition of Windows 10 that is designed for business or professional use. Windows 10 Pro can be activated using a digital license or a product key. None of these editions require reactivation every 180 days unless there are significant hardware changes or other issues that affect the activation status.

The technician should adjust the firewall settings to resolve the issue of not being able to access an internal site at https://companyintranet.com:8888. The firewall settings control how the firewall filters and allows network traffic based on rules and policies. The firewall settings may be blocking or preventing the access to the internal site by mistake or by default, especially if the site uses a non-standard port number such as 8888. The technician should check and modify the firewall settings to allow the access to the internal site or its port number. Default gateway settings determine how a computer connects to other networks or the internet.
Default gateway settings are not likely to cause the issue of not being able to access an internal site if the user can access the public internet. DHCP settings determine how a computer obtains its IP address and other network configuration parameters automatically from a DHCP server. DHCP settings are not likely to cause the issue of not being able to access an internal site if the user can access other network resources. IP address settings determine how a computer identifies itself and communicates with other devices on a network. IP address settings are not likely to cause the issue of not being able to access an internal site if the user can access other network resources. Antivirus settings control how the antivirus software scans and protects the computer from malware and threats. Antivirus settings are less likely to cause the issue of not being able to access an internal site than firewall settings, unless the antivirus software has its own firewall feature that may interfere with the network traffic.
