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 automatically delete, quarantine or rename the detected program or file, or ask you for a desired action.
