= File Integrity Checker =

The File Integrity Checker will compare your WordPress core files as well as your plugin and theme files to their original package. Its File Comparison Viewer will show you the differences between any modified file and the original. You can also [add your Premium themes and plugins](https://blog.nintechnet.com/ninjascanner-powerful-antivirus-scanner-for-wordpress/#integrity "") to the File Integrity Checker. Infected or corrupted files can be easily restored with one click.

= File Snapshot =

The File Snapshot will show you which files were changed, added or deleted since the previous scan.

= Database Snapshot =

NinjaScanner will compare all published posts and pages in the database with the previous scan and will report if any of them were changed, added or deleted.

= Anti-Malware Signatures =

You can scan your blog for potential malware and virus using the built-in signatures. The scanning engine is compatible with [Linux Malware Detect LMD](https://github.com/rfxn/linux-malware-detect "") (whose anti-malware signatures are included) and with some [ClamAV](https://www.clamav.net/ "") signatures as well. You can even [write your own anti-malware signatures](https://blog.nintechnet.com/ninjascanner-powerful-antivirus-scanner-for-wordpress/#signatures "").

= NinjaFirewall Integration =

If you are running our [NinjaFirewall (WP or WP+ Edition)](https://wordpress.org/plugins/ninjafirewall/ "Download NinjaFirewall") web application firewall plugin, you can use this option to integrate NinjaScanner into its menu.

= Fast and Lightweight Scanner =

NinjaScanner has strictly no impact on your database. It only uses it to store its configuration (less than 1Kb). It saves the scan data, report, logs etc on disk only, makes use of caching to save bandwidth and server resources. It also includes a Garbage Collector that will clean up its cache on a regular basis.

= Background Scans =

Another great NinjaScanner feature is that it runs in the background: start a scan, let it run and keep working on your blog as usual. You can even log out of the WordPress dashboard while a scanning process is running! You don't have to wait patiently until the scan has finished. Additionally, a scan report can be sent to one or more email addresses.

= Sandbox for quarantined files =

When moving a file to the quarantine folder, NinjaScanner can use a testing environment (a.k.a. sandbox) to make sure that this action does not crash your blog with a fatal error. If it does, it will warn you and will not quarantine the file. It is possible (but not recommended) to disable the sandbox.

= Advanced Settings =

NinjaScanner offers many advanced settings to finely tune it, such as exclusion filters, selection of the algorithm to use, a debugging log etc.

= Privacy Policy =

Your website can run NinjaScanner and be 100% compliant with the **General Data Protection Regulation (GDPR)**:

We, the authors, do not collect, share or sell personal information. We don't track or profile you. Our software does not collect any private data from you or your visitors.

== Changelog ==

= 3.0.10 =

* On websites running PHP 7.3 or above, NinjaScanner will use the hrtime() function instead of microtime() for its metrics, because it is more reliable as it is not based on the internal system clock.
* Fixed an issue where it was not possible to quarantine a file when running NinjaScanner on localhost over TLS because cURL reject the self-signed certificate.
* Fixed a bug with right-to-left (RTL) WordPress sites where the checkboxes below the log were all messed up.
* Updated Prism.js libraries.
* Small fixes and adjustments.

= 3.0.9 =

* Fixed a potential PHP "sprintf" fatal error that could occur if there were an error during the scanning process.
* Fixed a regex bug when checking for a Linux or Windows absolute path.
* Updated Prism.js libraries.
* Added more details to the scanner's log when a scan is cancelled because of an error.

= 3.0.8 =

* If the PHP ZIP extension, which provides the ZipArchive class, is missing on the server, NinjaScanner will fall back to the built-in PclZip library instead of refusing to run.
* When catching a PHP fatal error (E_ERROR), the scanner will write to the log the full path to the file where the error occured.
* Small fixes and adjustments.

= 3.0.7 =

* Fixed an issue during the anti-malware scan where the number of scanned items appeared to be higher than the total of files to be scanned, and returned an "Unknown Error" message.
* Fixed an issue where corrupted ZIP files downloaded from wordpress.org were not deleted.
* The anti-malware signatures file used during the scan will be temporarily saved to the database and no longer to disk because some antivirus used on Microsoft-IIS are still flagging the file as malware and delete it.

= 3.0.6 =

* Fixed a potential "Missing Lock File" error that may occur on slow servers.

= 3.0.5 =

* Fixed error introduced in 3.0.3 affecting PHP versions 7.1 and below.

* Fixed a potential "Undefined variable: snapshot" PHP notice.

* The temporary file used to saved antimalware signatures during the scanning process is now base64-encoded to prevent it form being flagged as malware by some hosting companies.

* Small fixes and adjustments.

= 3.0.2 =

* Fixed a potential issue where the scan could not start.
