What must a newly installed Deep Security Agent do to provide anti-malware protection?

To provide anti-malware protection, a newly installed Deep Security Agent must contact an update server. This step is crucial because the agent needs to retrieve the latest antivirus signatures and updates from the server to ensure its malware definitions are current. This updated information allows the agent to accurately detect and respond to any potential threats to the system.

By connecting to the update server, the agent ensures that it has real-time protection capabilities, allowing for the identification of the latest malware threats and vulnerabilities. Without this communication, the agent would be operating with outdated information, which could leave the system vulnerable to newly emerging threats.

The other options focus on actions that either are not necessary for initial setup or do not directly contribute to establishing malware protection right after installation. For instance, manual downloads might not provide the latest updates, while a full system scan, although important, is part of ongoing security maintenance rather than an initial step to activate protection. Disabling existing software could be an unnecessary action and might not be relevant unless it conflicts with the Deep Security Agent's operations.
