Scan WordPress Plugins and the entire website

To scan your blog plugins, you can start first with Virus Total before the upload, but then you need some specific plugins to search for malware and viruses.

1. Wordfence Security

This is the top WordPress security plugins that you should install, without a doubt, Wordfence is not a regular plugin that scans your website. But, it will do what you can imagine protecting your website, for example, if a plugin author adds a single letter in the plugin files just for an update. You will get an alert from Wordfense telling you about the exact location, and the line where the is a modification in the plugin.

Not all the security plugins can do that. At the same time, this plugin will scan your entire website every day.

If there is a new version of a plugin and you need an update, WordFense will send you an email about the plugin that needs an update. All the website files will be scanned periodically. If there are new attacks, the plugin will update your security automatically.

By the way, the plugin author is really active and send an instant email to webmasters when there is a new attack around the world. They compare the average attack number and alert people when an automatic manipulation detected from servers.

If you have problems with some IP or networks, you can block them with WordFense. It’s a powerful tool to protect and scan your entire website, in other words, it’s a plugin that every website should have.

Anti-Malware is a free WordPress malware removal plugin with powerful functions. It scans your entire website for malware, threats, and vulnerabilities in the server, it shows you a summary after the scan. If the site is OK, you see all in green. The best part of this plugin is to remove Known Threats.

So, you don’t need to search if what you see is normal or problem after the scan. They get signals from their network and mark the common viruses as “known”, to remove them automatically after verifying their hidden codes.

If there is a new information about new threats and malware, the WordPress antimalware plugin gets the update automatically, you can edit the scan settings or even run a scan from your dashboard.

3. Sucuri Security

The Sucuri Security is a WordPress malware removal service that will take care of your plugins and website in general, but it’s a great work will be to scan all your plugins, and search for hidden codes where your files can be opened without your permission.

This plugin gets details about any attack from different sources and compares results with theirs. Make sure to install this free plugin and run a scan.

So, this plugin understands exactly who they hide codes in your website and find them. Best of all, it shows you the hidden function.

Please don’t confuse the normal hide option in your theme and normal functions with the others. You will get many of the alerts, and you should delete only codes with URLs or negative impressions.

They can be installed instantly from your Dashboard, and you don’t need to pay for that great security level.
