Based on the settings of your F-Secure security product, it may block the file from running, move it to the quarantine where it cannot spread or cause harm, or remove it.
F-Secure's Security Cloud is an online service that tracks the security reputation of common programs, files and websites. If a questionable program or file is found during a scan, your F-Secure security product will send a query to the Security Cloud to get its most recent reputation rating. The product will then use that information (and if needed, further analysis) to choose whether to block, quarantine or remove the program or file.
The Security Cloud rating for the program or file indicates that it has code similar to backdoors - remote administration tools (RATs) that allow a user to remotely access and control a device, such as a computer or mobile device.
While backdoors can be used for legitimate activities by authorized administrators, they can also be used by attackers to gain control of a computer or device without the knowledge or consent of its user or administrator.
