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

AutoIt trojans are typically distributed as files attached to fake Instant Messager (IM) messages, or fake email messages.

Variants in the Autoit family attempt to download and install other harmful programs to the system; most variants will also try to change the startup and default search pages for the web browser (typically, Internet Explorer).

Some variants in this family may also delete various system files in order to prevent other applications, such as security programs, from functioning correctly.

For representative examples of variants in the AutoIt family, see:
