In the event of a detected virus, what can the client expect to receive from the firewall?

1. A completion notification for the download

2. A block page notification

3. A summary of the file content

4. A prompt to repeat the download

The correct answer is: A block page notification

When a virus is detected by a firewall, the most appropriate response is to provide a block page notification. This notification is an essential part of the security measures implemented by firewalls to inform the user that a potentially harmful file has been blocked from reaching their system. The block page serves several purposes: it alerts the user to the risk associated with the download, informs them that the file has been stopped before it could be executed, and often provides guidance or options for ensuring safer browsing practices in the future. This proactive measure is crucial for preventing malware infections and safeguarding the integrity and security of the network. The other options do not align with the standard response expected from a firewall in this situation. A completion notification for the download would imply that the download was successful, which would be inaccurate in the case of a detected virus. A summary of the file content is not typically provided, as the focus is on blocking the file rather than analyzing its contents in detail. Lastly, prompting to repeat the download would not be appropriate since the original attempt has been identified as a security threat. Thus, the block page notification is the correct and logical response in this scenario.
