Correct Answer: CTo detect malware on a laptop, the Antivirus security profile feature is most appropriate. Antivirus profiles are specifically designed to scan for and detect viruses, worms, trojans, and other types of malware in files, including those introduced via USB drives. This feature uses a stream-based malware prevention engine, which inspects traffic immediately upon receipt, providing protection without significantly affecting system performance. Other options like DNS Sinkhole or WildFire Analysis might help in identifying malicious activities or analyzing unknown malware, respectively, but for direct detection of malware on the laptop, Antivirus is the best choice.
