Removal

Automatic action

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.

Suspect a file is incorrectly detected (a False Positive)?

A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:

  • Check for the latest database updates

    First check if your F-Secure security program is using the latest detection database updates, then try scanning the file again.

  • Submit a sample

    After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.

    NOTE If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.

  • Exclude a file from further scanning

    If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.

    Note You need administrative rights to change the settings.

About Security Cloud

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.
