Summary


Security programs will sometimes unintentionally identify a clean program or file as malicious if its code or behavior is similar to a known harmful program or file. This is known as a False Positive.

See the Technical Details section for a list of the latest known False Positives, and the relevant remedial database updates.

Removal


In most cases, a False Positive is fixed in a subsequent database update; updating your F-Secure security program to use the latest database is enough to resolve the issue. You can take the following actions to handle a False Positive:

  • Check for a fix

    To check if your F-Secure security program is using the latest database update, see: Community: How do I know that I have the latest updates?

  • Submit a sample

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

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

  • Exclusion

    If you are certain that the detected file is a legitimate application or file, you may choose to exclude it from further scanning by the F-Secure security product.

Technical Details


False Positives sometimes occur if a program or file contains code or behavior that is similar to known harmful programs. This is especially likely if the program or file uses compression or protection techniques, or is spread using a distribution method, that are commonly used by harmful programs.
