Remove popup and plugin

Hello,

I had a WordPress project in the domain “washrocks.com” one month ago and now I have another project made with vueJS pointing to washrocks.com.

I dont know why the Hustle plugin is showing the popup yet. I’m not using WordPress in this domain right now and I have removed the campaing and the plugin from the original WordPress.

I think that this plugin is malicious and execute external code directly against the domain.

Please help me to remove and delete this nightmare.
