The term 'SWF' is used in an F-Secure detection name as a platform identifier to indicate programs that run on the Adobe Flash platform, a type of file format commonly used for multimedia presentations and interactive web applications.
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.
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.
To view SWF files (also known as Flash files), a user usually requires a separate 'player' application known as a Flash Player to be installed, usually as a plugin to their web browser.
Some malware are deceptively designed to mimic genuine Flash files, and are promoted to unsuspecting users using social engineering techniques in order to convince the user to execute the malicious file. A representative example of SWF malware is:
