A file or program that appears to have trojan-like features or behavior.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
Detailed instructions for F-Secure security products are available in the documentation found in the Downloads section of our Home - Global site.

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.
