Automatic action

Based on the settings of your F-Secure security product, it will either move the file 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.

Technical Details

An SMS-Worm is a type of worm that distributes copies of itself to new victims - in this case, mobile phones - over the Short Messaging System (SMS) of mobile telecommunications networks. An SMS-Worm may be able to automatically send a copy of itself to every contact listed in the mobile phone's Contacts list.

Alternatively, the SMS may contain a link to a website. On clicking the link, the user may inadvertently download the worm's executable code onto their mobile phone, thereby infecting themselves. For this method to work, the mobile phone would need to have Internet-access capability.

The SMS message will typically use an intriguing message in order to lure the user into reading and forwarding it, and possibly into clicking an included link.
