Hacked cisco router

Dears,

Someone hacked our cisco router. They create new username and password. I delete this username but when i do show running again I see this username and password. I upgrade the ios, reload the router but the problem is not solved. 

We do not want to delete the configuration file.

I think that they wrote  a script at TCL. How I fix this problem.
