Hi,
Combofix shouldn't be used by individuals unless you know what you are doing. Its a tool to help in the removal of malware, its not a scanner like MBAM is.
MBAM is excellent, always check for updates before using it. Its good practice to keep it (and all software) updated even if you dont scan that much.
Looks like a service may have been left behind:
look in C:/Program Files/Ares
you can delete the Ares folder.
start HJT, click the "Scan" button. check the items below, close any open windows, then click "Fixed checked"
O23 - Service: Ares Chatroom server (AresChatServer) - Ares Development Group - C:\Program Files\Ares\chatServer.exe
Hows it all looking on your end now?
