If You want to remove just search the file and then go to administrative tools- servcies and look for Remote administation or something similer and disable the service. set the startup type to disabled and then delete the file.

Not Dangerous if you installed it as part of remote administrator
Radmin, a remote control program like pcAnywhere. It has been incorporated into some worm/viruses without author's permission or knowledge. Only concern would be if you see it on your system and you did not install it intentionally.

This file is part of Radmin, a remote desktop application, from It would allow someone with the password to your server to gain control of it (but would probably be safe if your passwords are safe).

Best practices for resolving r_server issues

A clean and tidy computer is the key requirement for avoiding problems with r_server. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
