Summary

A Constructor is a malware creation toolkit that allows users with little technical knowledge to easily assemble a complex, malicious program from prepared 'building blocks' of code.

Removal

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.

Technical Details

Constructors come with a variety of options, ranging from very simple to very sophisticated. A typical kit is very easy to use, as it eliminates the need for programming knowledge and skills. A user can create malware simply by selecting the features desired.

A Constructor kit's ease of use is demonstrated by an incident in which an unknown person created more than 15,000 viruses using a constructor and sent them to antivirus companies. Fortunately, because the malware produced from these programs uses a finite set of code blocks and known polymorphic engines, they can be detected using Generic Detections.

The most famous Constructors are VCL, SennaSpy, BWG, PS-MPC, TPPE and IVP.
