Wp-config.php Malicious or Unsafe

Hello. I am having Wordfence find my wp-config.php file infected. It tells me that my file is infected with a backdoor. Wordfence tells me that they found a certain text match “include”.

I have no coding experience. Could I delete the exact code it detected from my wp-config.php file without making my WordPress site brake?

Have you experienced this before?

What are your thoughts?

Thank you in advance!
