TROJ_FRS.BMA000A815

This is the Trend Micro detection for Trojans that exhibit malicious actions such as modification of system settings, download and execution of arbitrary files, and stealing information.

Trojans are a general malware classification for malicious files, applications, or programs that may be bundled with malware or grayware packages. They may also be downloaded and installed unknowingly by users from the Internet. They may be also dropped by other malware onto the system.

Historically, people used Trojans to either further their research or gain notoriety. Now, cybercriminals use Trojans to gain profit by stealing user data like banking credentials and personal identifiable information (PII). They can sell this information in the cybercriminal underground or use it to launch other attacks such as phishing.

Some Trojans, coupled with social engineering techniques, are also capable of tricking users to do other activities. FAKEAV, for example, is a notorious malware family that displays phony alerts and scanning results to scare users into buying fake antivirus software. Trojans like RANSOMWARE can lock up files and systems, supposedly holding them captive. Users are not able to access their systems or files unless they pay ransom.

Trojans that modify an infected system's settings to automatically execute during startup may require procedures apart from scanning with an antivirus software.

If your Trend Micro product detects a file under this detection name, do not execute it especially if it comes from an untrusted or an unknown source (e.g., a website of doubtful nature).
