website is not running. Due to some malicous found

When I first visit the site, I see this:

To me, this looks like the website has been hacked. My recommendation: first read this article:

FAQ My site was hacked

After that I would recommend checking whether you still have a clean backup. If necessary, ask the support of your hoster. If so, delete all files and the database and restore the backup. Then change all access data in the hosting.

So if you still have a clean backup of your website, use that.

If you don’t have that, you can also hire someone to clean and secure it for you. However, this usually costs quite a bit of money. You can find offers for this online or you could ask here: https://jobs.wordpress.net/

Finally, you should secure your project. This is described in more detail in the article here: https://wordpress.org/documentation/article/hardening-wordpress/
