What Is Trojan.Farfli.FH?

Trojan.Farfli.FH is identified as a Trojan-type threat, which means it is designed to deceive users into installing it on their systems by disguising itself as legitimate software.

After successful installation, it can communicate with its command and control servers to receive instructions, which may include stealing personal data, downloading additional malicious software, or using the infected system for malicious activities such as spamming or DDoS attacks. Its ability to operate stealthily makes it challenging for users to detect without the aid of security software.
