Yep, it is always worth a shot to see if you can do a manual cleanup, but watch/monitor all of your sites like a hawk for at least a week. It can be a very time consuming thing to create multiple new websites if you have a lot of them under your hosting account. If you do end up having to install new sites then keep in mind that since WordPress Core/application files are easily replaced by deleting old Core files and uploading new Core files then there really is not any need to backup WordPress Core files. For your personal folders/files it is a good idea to back those up.
Yep, scanners cannot detect hacker files that are intentionally designed to be undetectable by scanners, which is really simple to do if the hacker uses standard PHP functions and does not use any typical obfuscation methods. Since all PHP code whether it is used for good or for bad is all the same PHP functions then scanners look for common standard PHP functions that hackers use. If the hacker file does not contain any commonly used PHP functions used by hackers or any obfuscated code then it will look like just a regular/standard/good php file to any scanners and they will not flag the file as suspicious or malicious.
