According to this test, your website has been hacked: https://sitecheck.sucuri.net/results/https/feruga.com

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 (also FTP, hosting login ..).

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 (and time for you if you try it yourself). You can find offers for this online or you could ask here: https://jobs.wordpress.net/
