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.

Technical Details

The MacKeeper program can either display pop-up ads during a web browsing session, or redirect users to unsolicited advertising content. Some users have also reported that the program causes performance issues for their devices.

The program may be installed as part of an application bundle. Users may be unaware that this program was installed if the application bundle did not clearly disclose the presence of additional programs during its own installation.

There have been reports that the MacKeeper program is difficult to uninstall, as users need to manually delete additional files that the program has saved on the machine, as well as uninstall extensions it has added to the browser, to completely remove the program.
