WordPress Virus Link Problem

Hi,

I think someone hacked my website. Because I received an email from google search console. And google showed me about 170 weird links on my WordPress website. That pages look real. But actually, they were not in my admin panel. I guess someone added to my database, WordPress files, theme files or plugin files. I want to show someone them.

Someone created a link under the category or looks like a post link.

I updated my WordPress, plugins and theme. But I am sure I will have a similar problem. That’s why I have a question.

How can I know or how can I get a notification if someone adds a link to my database or theme files…?

I am using a security plugin. But it doesn’t have such features.

Thanks
