Incomprehensible requests to the site. Is it a virus?

Question

Malware

Good afternoon. Analyzing the access.log, I saw regularly repeated requests like
site.ru 5.155.65.45 - - [28/Mar/2018:11:56:36 +0300] "GET /wp-content/uploads/debug-wp.php HTTP/1.1" 404 1322
What is this? The rest of the virus? Where are they climbing from? Aibolit finds nothing?

Answer 1

Automatic vulnerability scanner. Someone with ip 5.155.65.45 is trying to find a hole in you. Your site has nothing to do with it.

Answer 2

What is it? The rest of the virus?

Do you understand what access.log is?
And there are viruses on your site.
Bots constantly scan sites for holes or just brute.
