My website has been hacked by Drac-101 code

My website has been hacked. However, I have been able to reload the files the hackers had changed and my website is opening now. But I have a major issue. The original wordpress admin name and password has been changed by the hackers to “ubh”. This I realized when I could not log in and had to ask for a new password through “Forgot password” option. When I received the link for changing my password I got the “name” that the hackers have used. For a quick solution to setup my website I have used the new hackers “name” and managed. But this seems a bit dicey as the hackers can attack again. Should I re-instal WordPress again with a new name of my choice?
