RCServ, Backdoor.RCServ


The RCServ is a backdoor - hacker's remote access tool. The backdoor consists of a server and of a client part. The server part should be installed on some computer so that a hacker could access it using a client part. The server part provides a hacker with information about an infected system, user actions and it also allows him to get a limited access to data on an infected computer. The RCServ backdoor server allows multiple connections, so several hackers can use the same server at the same time.


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.
