Summary

FjCon.A monitors incoming messages, and blocks those containing certain contents from showing up in the inbox.

Removal

Once the scan is complete, the F-Secure security product will ask if you want to uninstall the file, move it to the quarantine or keep it installed on your device.

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 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.

FjCon.A is signed with a key trusted by common custom ROM builds, allowing it to obtain permissions that are usually not needed in typical applications. For example, the INSTALL_PACKAGES and DELETE_PACKAGES allow it to remotely install an application or package onto the device without the user noticing.
