What exactly are those files that get listed under read/write errors?
Does the fact that they are read/write errors necessarily mean that they are problematic?
What should be done about them? Can they be ignored? Do they need to be investigated further? Should they simply be deleted?
Here is an edited sample of one batch of files that came up as read/write errors during an anti-malware scan:
A Read/Write Error simply means that my plugin was unable to read (or, when attempting to fix a file, write to) that file, usually because of the file permissions but sometimes it is because of the files size and/or the memory_limit being set too low in your php.ini file. It does not necessarily mean that those file are bad or malicious but it is an indication that there is some kind of issue on your server that needs to be investigated further. I would never suggest anyone delete files on there server just because there was a read/write error, but if you are able to download and open the files and you find the contents to be completely malicious then you can delete them for that reason (remember that some files that contain malicious code may also have code in then that your site need in order to function correctly).
