The most likely reason for the antivirus protection on a company laptop being out of date is failed OS updates1. Antivirus software relies on the operating system to function properly. If the operating system is not up-to-date, the antivirus software may not function properly and may not be able to receive the latest virus definitions and updates2. Therefore, it is important to keep the operating system up-to-date to ensure the antivirus software is functioning properly2.

The technician should not proceed with initiating a full scan and removal of the viruses using the presented interface or call the phone number displayed in the interface of the antivirus removal tool12

Shutting down the infected computer and swapping it with another computer is not necessary at this point12

The technician should not immediately assume that the message is legitimate or perform any actions without knowing what the interface is and what triggered it to pop up. It is important to investigate the issue further, including checking the legitimacy of the antivirus program and the message it is displaying.

To exclude an application folder from being cataloged by a Windows 10 search, the technician should use the Indexing Options utility1

For scripting the creation of Active Directory accounts, PowerShell (D) is used. PowerShell is a task automation and configuration management framework from Microsoft, consisting of a command-line shell and the associated scripting language. It is built on the .NET framework and is particularly suited for automating and managing Windows-based systems, including Active Directory tasks​​.

The file type that the technician will MOST likely use when installing new software on a macOS computer is .app. This is because .app is the file extension for applications on macOS1.

Authenticator applications are designed to enhance security by generating temporary, time-sensitive passcodes used in two-factor authentication (2FA) processes. These passcodes are used in conjunction with traditional credentials (like usernames and passwords) to grant access to systems or applications. This extra layer of security ensures that even if primary login credentials are compromised, unauthorized access is still prevented without the dynamically generated code from the authenticator app.

DNS (Domain Name System) lookups are essential for translating human-friendly domain names into IP addresses that computers use to communicate. DNS typically uses port 53 for its communication.

In the provided firewall output, various ports are either allowed or blocked for outgoing traffic. For DNS recursion, which is the process of resolving domain names to IP addresses, port 53 must be open.

Port 53: This is the standard port used by DNS for queries and responses. The fact that it is currently blocked (as per the firewall output) is the reason why DNS lookups are failing. Opening port 53 will allow the DNS requests to pass through the firewall, enabling the resolution of domain names to IP addresses.

Other ports mentioned in the output are used for different services and protocols:

Port 1 is generally not used for standard services.

Port 445 is associated with SMB (Server Message Block) for file sharing in Windows environments.

Port 123 is used by NTP (Network Time Protocol) for time synchronization.

Port 80 is used for HTTP traffic, which is web traffic but not related to DNS lookups.

For securely disposing of SSDs, physical destruction methods like shredding are considered most effective:

Shredding: This method involves physically breaking the SSD into small pieces, making data recovery practically impossible. It's a recommended practice for ensuring that sensitive data on SSDs is irretrievably destroyed.
