If this is happening, there must be a radmin server installed on your computer. Remove the server and you will be free again.
To remove the server go to the installed programs and uninstall Radmin. If you can't find anything installed, look for r_server.exe on your system and try to remove the file. r_server.exe will also be visible as a running process, so you might have to stop te service first.
The easiest way to remove RAdmin is to go into Start->Settings->Control Panel->Add/Remove Programs, select "Remote Administrator" and press "Remove" ("Uninstall") button.
If there's no "Remote Administrator" entry in software list, it means that RAdmin was installed manually.
First of all, you must locate "r_server.exe" file on your computer.
Usually it's located in C:\Program Files\Radmin. If not, go into Start->Search->"For Files of Folders...", type "r_server.exe", ensure that "Look in" setting is set to "Local harddrives" and press Enter.
Run r_server.exe with "/stop" command-line switch. Then you must run it with "/uninstall" command-line switch to prevent it from starting automatically. After that you can delete this file.
To run a program with command-line switch, you must select "Run" command from Start menu, then type r_server.exe with full path encapsulated in quotas, than space and then required command-line key (for example, "C:\Program Files\Radmin\r_server.exe" /uninstall).
Next go into Start->Search->"For Files of Folders..." again, type "admdll.dll", ensure that "Look in" setting is set to "Local harddrives" and press Enter. Delete found admdll.dll files.
Now Radmin Server should be uninstalled from your computer.

You also should install the software ZoneAlarm or some other firewall software that would prevent or at least ask you for internet access before it would be allowed to run. You were infected somehow but the lack of security for your computer is really what should alarm you more than having RA installed.
