File sent to Quarantine

[Ian]

Hi,

We have not been working on the website this afternoon, and I have just had an email to say the following files have been quarantined which sounds suspicious.

Do you recognise any of these files, and should we do anything in particular – This is the first time something like this has happened to us.

These are all legitimate WP Core files. So either a WP Automatic update occurred and these files were accidentally quarantined or these files have been tampered with. Most likely this is an accidental quarantine.

Use FTP or your web host control panel File Manager tool
Download /wp-includes/class-wp-http-ixr-client.php to your computer.
Download /wp-includes/nav-menu.php to your computer.
Email these 2 files to info@ait-pro.com so I can check them.

This problem was handled via direct email. The files sent to me were checked by me and they had not been tampered with. AutoRestore|Quarantine accidentally quarantined legitimate WP Core files during the recent WP 6.9.4 Automatic Update. This problem can happen if there is significant latency when the WP update occurs. The solution is to restore the WP files in Quarantine.
