apache - Someone put malicious code with "~" on my website

Question

I made my website in www.mantarrayamx.com and everything worked well, but today I got a message from google telling me that someone is misusing my website through this address: Http://www.mantarrayamx.com/~stechies/Blessin/ba/ Does anyone know how I can solve this security problem please?

Answer 1

After some research, I found that the ~stechies means, home directory of a user perhaps "stechies". I found a website with the same a domain name https://www.stechies.com/ I am not sure if they are behind this or they are hacked as well.

Any help to stop this redirection is much appreciated.
