What security solution should be recommended to protect against Trojans?

The correct recommendation for protecting against Trojans is antimalware software. Trojans are a type of malicious software that disguise themselves as legitimate programs to gain access to a user's system. Antimalware software is specifically designed to detect, quarantine, and remove various types of malware, including Trojans. It routinely scans files and programs on the system, ensuring that any suspicious behavior is identified and handled promptly.

While antivirus software is also a formidable defense against malware, the term generally refers to protection against viruses specifically. Many modern solutions classify themselves as both antivirus and antimalware, suggesting that they can handle various types of threats. However, “antimalware” emphasizes broader coverage that includes Trojans and other forms of malicious software.

Other solutions, such as firewalls, serve to monitor and control incoming and outgoing network traffic but do not inherently detect or remove Trojans that may already be on a device. Similarly, encryption tools are useful for securing data but do not provide any direct protection against malware that may infiltrate a system. Given this context, antimalware software stands out as the most effective solution for combating Trojans specifically.
