Your WordPress site hacked? Malcure scans files AND database to find and help you remove malware casual scanners miss. Free. No bloat.

== Description ==

Is your website acting strangely? Seeing 'Deceptive Site Ahead' warnings, Japanese spam, SEO spam, or random redirects? Time to fix and monitor your site with **Malcure Malware Shield**.

**Malcure Malware Shield scans for infections, runs silent scheduled scans, and sends alerts before threats spread — turning one-time cleanup into always-on protection.**

== Malcure Malware Shield: The Powerful Antivirus ==

Just as your computer requires antivirus, your website demands specialized **antivirus-grade protection**. Malcure Malware Shield delivers comprehensive, **antivirus-style** detection with advanced signatures to identify viruses, trojans, backdoors, adware, and ransomware. Unlike basic security plugins, it operates with the precision of an antivirus engine, scanning every layer of your site—from core files to the database—to ensure your website remains virus-free and secure.

== Malware Removal, Hack Repair, Monitoring & Protection ==

Malware attacks are evolving. Standard scanners often miss hidden backdoors and database infections. If your current security plugin says "All Clear" but your site is still broken, you need **Malcure Malware Shield**.

**Malcure Malware Shield** is the intelligent, lightweight security solution. We believe security should be simple on the surface but deep under the hood. No complex settings. No bloat. Just activate and scan.

Lightweight, API-driven scanning runs only on demand or on scheduled scans — no persistent background processes.

Unlike scanners that delay new malware definitions for days, Malcure delivers real-time threat intelligence to every user so you’re protected against the latest threats as soon as they emerge.

== What Our Users Say ==

Quotes are verbatim from WordPress.org support reviews, except for bracketed edits (for example, competitor names removed).

= Best by far, better than [competitor name removed] and other giants =
> "You can see it is a bunch of geeks that created this, with skill and visual creativity at that. I spent hours trying to find a plugin like this. So many options and such bad results until now. Great job guys. You deserve it. Simple and effective. (Disclaimer to other potential readers: there are many types of hacks/malware out there, every scenario is different, but start with the Malcure scan and see how it goes. 9/10 you won't be disappointed, my guess)" — [@dalingzaf](https://wordpress.org/support/topic/best-by-far-better-than-wordfence-and-other-giants/)

= The ONLY plugin that scans files... =
> "I am a web developer and have tried many malware removal plugins, including popular ones [competitor names removed]. However, none of them detected some unusual files that were actually malware causing regular attacks. Some of these files were in JPG format." — [@devzeeshanx](https://wordpress.org/support/topic/the-only-plugin-that-scans-files-in-real-time-2/)

= Best Malware Removal Plugin in just few minutes =
> "Most security plugins that are free only scan the code, but Malcure Malware Removal Plugin scans the wordpress database and the code files in few minutes. Accurately shows which Database table row is infected and it helps resolve the hacking attempt instantly. Saves a lot of time for the developers. Thank You Team Malcure" — [@s3630](https://wordpress.org/support/topic/best-malware-removal-plugin-in-just-few-minutes/)

= It's not just a "teaser" =
> "This plugin really found the malware, and removed it. Really for free. Thanks guys, I'm going to donate now!" — [@halucska](https://wordpress.org/support/topic/its-not-just-a-teaser/)

== Malware Removal & Hack Repair ==

-   **Checksum Verification:** We verify core, plugin, and theme file integrity against the official repository checksums served by our SaaS API endpoint.
-   **Deep Scan:** If checksums fail, Malcure runs a full scan against malware detection signatures detecting estimated 50,000+ variants.
-   **Inspect & Repair:** Inspect infected database records and files. Assists in cleaning compromised files and database entries.
-   **SEO Spam Specialist:** Detects and removes the notorious “Japanese Keyword Hack” and pharma spam from your files and database, helping restore your Google rankings.

== Virus Scanner & Threat Detection ==

-   **Database Scan:** Scans database tables for malicious injections and spam links.
-   **User Scan:** Scans users and their metadata for signs of compromise.
-   **File Scan:** Scans core files, themes, plugins, images, and uploads for backdoors and obfuscated code.
-   **Vulnerability Detection:** Checks your core, plugins, and themes for known security flaws.
-   **DeepScan™ Technology:** Scans backups, archives, images, and hidden files where malware hides.
-   **Ultra-High Precision:** Uses intelligent checksum verification (comparing your files to official core/plugin/theme checksums) to dramatically reduce false alarms compared to heuristic-only scanners.

== Intelligent Health Monitor ==

-   **Always-On Guard:** Continuous monitoring via **Scheduled Scans** (daily/weekly/monthly) configurable cadence.
-   **Instant Alerts:** Every time a scheduled scan completes, you get an instant email report telling you if your site is clean or infected.
- **Weekly Reports:** Receive a comprehensive weekly report summarizing your site's security status.
-   **Event Log:** Track the events leading up to a malware incident for faster root-cause analysis.

== Powered by Malcure API: Real-Time Threat Intelligence ==

Hackers don't sleep, and neither do we. Malcure Malware Shield connects to our real-time API to fetch the latest threat definitions.

This plugin relies on the Malcure API to provide real-time threat intelligence and checksum verification.

-   **Data Transmission:** To perform scans, the plugin sends file checksums and your site's domain to Malcure servers. No sensitive user data is transmitted.
-   **Terms & Privacy:** Use of the API is subject to our [Terms of Use](https://malcure.com/?p=1720) and [Privacy Policy](https://malcure.com/?p=3).
-   **Zero-Day Alerts:** Our API serves new threat-intelligence in real-time, ensuring the site is scanned against the latest vulnerabilities.
-   **Smart Checksums:** We verify your core files, themes, and plugins against the official repository checksums using our API, ensuring absolute integrity.
-   **Lightweight:** The scanner only uses minimum resources to keep your server fast and responsive.

== Reinfection Risk & Continuous Monitoring ==

Malware cleanup is not a one-and-done task. New vulnerabilities and reinfections can appear without warning, so continuous monitoring and scheduled scans help catch issues early—before SEO damage, blacklists, or downtime. You get email notification with the results to rest assured that the site is clean or when immediate action is required.

-   **WooCommerce / membership / lead-gen sites** where downtime, SEO brand-reputation damage are expensive.

Malcure Malware Shield is extremely thorough and leaves no aspect of the site to speculation. Try Malcure Malware Shield to experience exceptional thoroughness and speed in removing website malware and ongoing security.

= Will Malcure Malware Shield impact the performance of my website? =

Malcure Malware Shield only runs when you want it to or when it is scheduled to utilizing minimal resources. At all other times it sleeps silently. The firewall triggers extremely quickly and is optimized for performance.

= Where can I find the Malcure Terms of Use and Privacy Policy? =

These are available on our website: [Terms of Use](https://malcure.com/?p=1720) and [Privacy Policy](https://malcure.com/?p=3)

= Will this slow down my website? =
No. Malcure is engineered to be lightweight. We don't run heavy background processes that eat up your server CPU like other "bloated" security plugins. Malcure runs only when you trigger a scan or schedule one.

= Can I clean my hacked site for free? =
Yes. The free version identifies every single infection (file path & line number). You can use this report to manually clean your site. The premium Malcure Advanced version offers deletion of irreparable files if you want to save time.

= How is this different from other plugins? =
Malcure is focused on simplicity and performance. We don't have days of delay on detection signatures—you get updated signatures instantly for free. We also scan your database for hacks, which many file-only scanners miss.

= Does it match "False Positives" like other scanners? =
Malcure Malware Shield uses intelligent checksum verification against the official core/plugin/theme files. This drastically reduces false alarms. We focus on being precise so you don't get false alerts and anxiety.

= Why do I need to register? =
Registration connects your site to the Malcure API enabling real-time threat intelligence. It's free and ensures you get the best protection.

= Does this plugin remove malware automatically? =
The free version detects malware with high precision and allows repair of official core/plugin/theme files. The [Advanced Edition](https://malcure.com/?p=116) offers deletion, whitelisting as well as advanced features for infected files.

= What data is sent to the Malcure API? =
To perform scans, the plugin sends file checksums and your site's domain to Malcure servers. No sensitive user data or file contents are transmitted unless you explicitly use the "Inspect File" feature.

= What's the difference between Free and Advanced? =
Both editions scan files and the database, verify core/plugins/themes integrity, and include firewall/hardening features.

The Advanced Edition adds Whitelisting, Advanced Scan Filters, File Operations, WP CLI Automation, Deployment, Bulk Client-Servicing Features, Background Scan & Premium Support (Expertise), and high-priority support.

= How should I interpret results like "infected" vs "suspicious"? =
"Infected" generally means that Malcure has high confidence the code matches malicious patterns.

"Suspicious" can indicate risky/obfuscated behavior or something that warrants review (for example, heavily minified code or unusual PHP patterns). If you're unsure, use Inspect (Advanced) or [contact support](https://malcure.com/?p=157).

== Troubleshooting ==

= Some files are detected by Malcure Malware Shield as "suspicious". What gives? =

Malcure's DeepScan checks each file for malware. However some files aren't pure malware but may contain code that is suspicious and could potentially do nasty things. You should carefully review and analyse them to see if they indeed do anything nasty.

= I can't get Malcure Malware Shield to work. It hangs / doesn't complete the scan / breaks for some reason. =

If you think that the plugin is broken, [please report it here](https://malcure.com/?p=5677).

Malcure Malware Shield (or for that matter other plugins) may break on malware affected / broken websites. [Malcure Advanced Edition](https://malcure.com/?p=116) integrates with WP CLI and allows you to complete the scan from WP CLI even when the site is blocked by the webhost or when you are unable to login to the website.

= My site is infected however Malcure Malware Shield doesn't detect the infection. =

Malware keeps evolving. If you come across malware that Malcure Malware Shield is not able to identify, you may [please report it here](https://malcure.com/?p=157).

= The scan gets stuck midway. What should I do? =

In case of such an event, please file a support request with us and we'll be more than happy to troubleshoot the issue.

Please visit [this page](https://malcure.com/?p=5677).

= I cleaned my site but it got infected again. What should I do? =

Malware cleanup is a waste of time and effort unless you find the root cause behind the malware infection and monitor for recurrence. How was someone able to infect your website? Have you plugged in that security hole?

Please read [Why Do Websites Get Hacked](https://malcure.com/blog/security/why-do-wordpress-websites-get-hacked/).

= Google Safe Browsing site status (or some other scanner) still shows my site as infected. What should I do? =

First make sure you purge your site cache. Second, Google (and other scanners) cache the results for some time. You'll need to force or refresh the scan. You can also file a request with us to [get your site off any blacklists](https://malcure.com/?p=107).

= I found a suspicious file, what now? =

If Malcure flags it, it's likely malicious. You can inspect the file content using our built-in inspector. If you're unsure, consider our [Expert Malware Removal Service](https://malcure.com/?p=107).
