Riskware:W32/Realvnc.A, Riskware:W32/Realvnc


A legitimate application that may introduce additional security risks or be used for malicious purposes.


Based on the settings of your F-Secure security product, it may allow the file to run, block it from running, move it to the quarantine where it cannot spread or cause harm, or ask you to select an action.

If you are aware of the risks involved in using the file and consent to its use, you may change the settings of your F-Secure security product to allow the file to run. You may also change the settings to exclude it from scanning.

Note: You need administrative rights to change the settings.

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

Application:W32/WinVNC is a remote administration utility program for use in observing or administering a remote machine.

Though legal, usage of this program may be considered unlawful in certain jurisdictions, if it is used to manipulate a computer without the knowledge and/or authorization of the machine's primary user.


Like backdoor programs, WinVNC comprises of two components: a server and a client. To control a remote computer, the server component must be installed on the targeted machine. This may or may not be done with the authorization of the computer's primary user.

Once the server component is installed on the targeted machine, an authorized administrator (or attacker) can use the client component to communicate with it, and in turn observe and control the computer.

Note: an icon may be displayed on the computer to indicate the presence of the server component; the icon may however be disabled.
