Which statement about antivirus filtering is supported by the material?

• A. Antivirus filtering is not provided by any firewall
• B. Antivirus filtering is provided by UTM firewalls
• C. Antivirus filtering is only available as an add-on external appliance
• D. Antivirus filtering is the same as IDS service

Answer: (B)

Antivirus filtering is typically built into Unified Threat Management (UTM) firewalls, which bundle multiple security functions into one device. A UTM not only controls traffic with a firewall but also scans it for malware, checks file attachments, and blocks malicious content before it reaches endpoints. This integrated antivirus capability is a hallmark of UTMs, distinguishing them from plain firewalls and from external add-ons. The material commonly describes antivirus filtering as a native feature of UTMs, rather than something only available as a separate appliance or not available at all. It’s also a different service from IDS/IPS, which focuses on detecting suspicious activity in traffic rather than scanning files for malware.
