Suspect A False Alarm?

If you suspect a file has been incorrectly identified as malicious, (that is, it is a False Alarm or a False Positive), please first ensure your F-Secure security program is up-to-date with the latest detection database updates, then rescan the suspect file.

If you continue to suspect a False Alarm, you may submit a sample of the suspect file to our Security Labs for further analysis via the Sample Analysis System (SAS).

Technical Details

Named after the Trojan Horse of Greek legend, a trojan is a program that performs, or appears to perform, one function, but in reality executes another action without the user's knowledge or consent.

Usally, a trojan program will either have (or pretend to have) a functionality that offers a useful service to the user - for example, a screensaver, a service pack or application update and so on - to encourage the user to install the program. Some trojans may use similar or even identical styles, colors and designs as those of legitimate programs, to further deceive the user.

Once installed, the trojan performs its actual, unauthorized function, which can range from mildly annoying pranks (like changing desktop icon positions), to serious, user-inhibiting functions (like disabling the keyboard or mouse) to critically destructive actions (like erasing files or stealing data).

A trojan that is identified by a detection using the format 'trojan.generic.[variant]', 'trojan.gen.[variant]' or similar indicates that the program was identified by a Generic Detection. Unlike single-file detections which identify unique files, a Generic Detection looks for broadly applicable code or behavior characteristics to evaluate a file's potential for causing harm; a single Generic Detection can therefore efficiently identify dozens, or even hundreds of malware.
