wp-login.php in strange location [closed]

I have a problem, in my wordpress the wp-login appears in a strange location myweb.com/covid-19/wp-login.php and it should be myweb.com/wp-login.php. I have searched it in the source code and in the database to eliminate it but I have not been successful.

disable all plugins and the link disappears, but after a while it reappears.

I have performed the following tasks: scan virus and all have given negative

Any ideas?
