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

Trojan:W32/Vawtrak is distributed as part of the payload of various exploit kits, and via spam email campaigns.

Once present on a device, Vawtrak malware is capable of creating VNC and SOCKS servers (that allow an attacker to access the affected device), capturing screenshots and video, and a variety of other actions. The main aim of the malware is to steal login credentials (most significantly, for online banking portals) from various sources on the device, such as the web browser, email clients and FTP clients. It may also inject and display fake web forms in the web browser to lure the user into giving away their sensitive details.

The malware can also contact a remote site (its command and control centre) to obtain further instructions from its controller(s).
