Last Updated on December 1, 2025 by RADHIKA

Protect your WordPress site using real, tested free methods. Learn how TechFin2k secured WordPress with free plugins, SSL setup, and smart hosting — plus trusted recommendations for affordable upgrades.

Introduction: Why Security Matters in 2025

WordPress powers over 43% of all websites worldwide, which unfortunately makes it one of the top targets for cyber-attacks. According to security data, cyberattacks rose by 38% in 2025, with small business websites being the most affected.

As a site owner myself, I’ve seen how quickly malware or a small vulnerability can damage traffic, reputation, and SEO rankings. So, I decided to test free WordPress security methods on my own site, TechFin2k.com — and here’s what really works.

💡 The good news? You don’t have to spend $99 a year on plugins. With a few smart steps and free tools, you can harden your site’s defenses for zero cost.

In this video, I intentionally infected my own WordPress site with a test virus (EICAR file) to see which popular “free” security plugins could actually detect and remove it without asking for money.

Watch the full test here:

🔍 What Makes WordPress Vulnerable?

WordPress’s open-source flexibility is its strength — but also its weakness if not maintained correctly.
Here are the top vulnerabilities I discovered during my audit:

1. Outdated Plugins & Themes
   Over 70% of hacked sites were running outdated software. Attackers constantly scan for known vulnerabilities in old plugins.
2. Weak Admin Passwords
   Brute-force login attacks happen thousands of times per minute. Simple passwords are like leaving your front door open.
3. Insecure File Permissions
   Loose permissions or writable config files can allow backdoors for malware.
4. No SSL Certificate
   Sites without “https://” are marked as Not Secure by browsers and penalized by Google.
5. SQL & XSS Exploit
   Improper input validation in forms or themes can leak your database or inject malicious code.

🔐 Free WordPress Security Plugins That Actually Work

I tested three popular plugins directly on my site to check which ones offer the best mix of malware detection and actual removal for free.

How I Tested the Malware Detection (Safe EICAR File Test)

To test whether these WordPress security plugins actually detect malware, I used the official EICAR test file, which is a completely safe and widely used antivirus testing script. It does not harm your website, database, hosting, or files in any way — it is only designed to trigger antivirus and security scanners.

For full transparency, here is the exact test file I used:

I uploaded this file directly to my WordPress installation using the Hostinger File Manager.

👉 Important Note:

• This is the standard EICAR test file, used globally for antivirus testing.
• It is 100% safe, does not harm your website, and contains no real malware.
• I tested this on my subdomain, not on my main production site, strictly for educational and review purposes.

The purpose of using this file was simple:
✔ To check if Wordfence, MalCare, and Sucuri can detect it
✔ To see whether the free versions show the file name and location
✔ To confirm which plugin allows malware removal without upgrading

This method provides a fair, real-world test of how each plugin behaves when an actual suspicious file is uploaded.

🧱 I. Wordfence Security (Free) – The Real Winner

To evaluate how Wordfence performs in real-world malware detection, I installed and tested it on my own WordPress subdomain. Here is the exact process I followed.

1. Installing Wordfence Security Plugin

I first installed Wordfence Security from the WordPress plugin directory. During the installation, Wordfence asked me to enter a license key to complete the setup.

Even though Wordfence offers a completely free version, it still requires free registration to activate malware scanning features.

2. Registering for the Free License

I selected the Free Plan, entered my email address, and created an account. The free plan is enough for scanning and removing malware, but it delays some advanced threat intelligence by 30 days — which is perfectly fine for testing.

Within a few seconds, I received the free license key in my email inbox.

I copied that key and pasted it into the Wordfence setup wizard to complete the installation.

3. Running the Full Site Scan

After the installation was complete, I opened the Wordfence dashboard and clicked Scan to run a complete malware and vulnerability check.

Wordfence scanned:

• All WordPress files
• Themes and plugins
• Database tables
• Custom files
• Suspicious PHP code
• Malware signatures
• Modified core files

4. Wordfence Detected the EICAR Test File

As part of my test, I had uploaded the EICAR test PHP file earlier (on my subdomain).
Wordfence immediately detected it as malicious, clearly showing:

• File name
• Reason it was flagged

This is the most important part — Wordfence shows everything clearly, unlike the other plugins.

5. Removing the Malware Using Wordfence Free

Wordfence gave me multiple cleanup options, including:

• Delete the file
• Delete related tables
• Repair the file (if it’s a modified core file)

Since this was a test, I selected Delete All Tables / Delete File.

Within seconds, the file disappeared from my Hostinger File Manager.
This confirmed that Wordfence actually removes malware in the free version, without upsells, restrictions, or forcing a premium upgrade.

Best for: Malware detection, firewall, and free cleanup.

• Real-time firewall with brute-force defense
• Detailed scan reports (infected files + known vulnerabilities)
• Option to block malicious IPs

Test Result (TechFin2k):
✅ Detected all sample malware files I uploaded for testing.
⚙️ Minimal speed impact on shared hosting.

II. Sucuri Security Plug-In (Free Version)

Next, I tested the Sucuri Security plugin to see how well it identifies malware in the free version. Sucuri is popular for website monitoring and file integrity checking, so I wanted to understand how it performs when an actual suspicious file exists.

1. Installing Sucuri Security Plugin

Sucuri is simple to install because it does not require any registration or account creation. Once the plugin was activated, the dashboard immediately showed basic security information about my site.

2. Running the Security Scan

Sucuri’s free version does not include a deep internal malware scanner like Wordfence or MalCare. Instead, it provides:

• File integrity check (core files comparison)
• Heuristic alerts
• Modified file detection
• Audit logs

When I ran the scan, Sucuri checked my WordPress core files to identify whether anything had been modified or injected.

3. Sucuri Detected the Modified File — But No File Path

Sucuri did detect that “WordPress core files were modified,” which confirms that the Sucuri free plugin can recognize suspicious activity.

It also displayed the name of the suspicious file, including the EICAR test file I uploaded.

However, the major limitation is:

• ❌ Sucuri does NOT show the file location (file path)
• ❌ Sucuri does NOT show the file location (file path)
• ❌ No ability to repair or delete the infected file

This means you only know something is wrong, but you cannot see:

• Where the file is stored
• Which folder it belongs to
• How to manually remove it

Without the file path, removing malware becomes difficult for beginners.

4. Good for Monitoring – Not for Malware Cleanup

Based on this test, Sucuri’s free version is useful for:

• Identifying that a file has been modified
• Notifying you that suspicious files exist
• Highlighting unusual changes in your WordPress installation

But it is not useful for actual malware removal.

You cannot:

• See the exact folder where the malware is located
• Remove or repair files
• View full details

To fix anything, you would need a developer or a different plugin (like Wordfence).

⭐ Sucuri Free Test Summary

Sucuri works as a warning tool, not as a full malware removal solution.

🤖 III. MalCare Plug-In (Free)

Finally, I tested the MalCare Security plugin to understand how its free version handles malware detection and cleaning. MalCare is known for cloud-based scanning, so I wanted to check how effective it is when an actual suspicious file exists on the site.

1. Installing MalCare Plugin (No Registration Needed)

MalCare was very easy to install because it did not ask for any license key or account registration during setup.
After activation, the dashboard showed a simple interface with a “Scan” option.

2. Running the Malware Scan

I clicked the Scan button, and MalCare performed a cloud-based scan of my website.
The scanning process took some time, and within a short time, MalCare displayed the results.

3. MalCare Detected Malware — But Showed No File Name or Location

MalCare flagged the site as:

• “Hacked”
• “1 malicious file found”

However, the free version did not provide any details about:

• Which file was infected
• Where the file was located
• The folder path
• What type of infection was detected

This makes it very difficult for a beginner (or even an experienced user) to take action.

4. Clicking “Review Malware” → Forced Upgrade

MalCare displayed a Review Malware button, so I clicked it to view more details.

Instead of showing the infected file, MalCare displayed an upgrade screen stating:

• “Unlock auto malware removal”
• “Powerful advanced features”

This means the free version does not allow you to review the actual malware file. The image below shows the upgrade prompt to review the malware.

5. Clicking “Clean Now” → Upgrade Required ($176.40/Yr)

I also tested the second button — Clean Now.

MalCare again displayed a premium upgrade message with pricing:

• $176.40 per site per year
• “Guaranteed clean-up”
• “Instant malware removal”

At this point, it was clear that the free version:

• ❌ Does NOT clean malware
• ❌ Does NOT show the malware file name
• ❌ Does NOT show file path
• ❌ Does NOT provide any actionable information

⭐ MalCare Free Test Summary

✔ What MalCare Free Does Well

• Quick cloud-based scanning
• Detects malware presence

✘ What It Does Not Provide

• No details about infected files
• No file location
• No free cleanup
• All useful features locked behind premium upgrade

MalCare is a good scanner, but its free version is not suitable for malware removal, especially for beginners.

🔍 Comparison: Wordfence vs MalCare vs Sucuri

📌 My Real-World Test Results (Based on EICAR Test File)

• Wordfence: Successfully detected the test file, showed full details (filename + path), allowed deletion/cleanup → ✅ Fully effective in free version.
• MalCare: Flagged the site as hacked / malicious file found — but no details or file path shown → ❌ Free version not useful for cleanup or manual removal.
• Sucuri: Indicated modified core / suspicious files — but did not show file path or provide any cleanup option → ⚠️ Only useful as a warning monitor, not for removal.

🎯 Who Should Use What (Based on Your Needs)

• ✅ Use Wordfence Free: If you want a truly free, end-to-end solution — scanning + detection + cleanup + firewall protection. Best for bloggers, small business sites, beginners.
• ⚠️ Use MalCare Free (with caution): If you only want to check if your site is hacked (not clean it). Paid plan required for actual cleanup.
• ⚠️ Use Sucuri Free (for monitoring only): If you want occasional integrity checks or light monitoring — but be ready to manually remove malware or upgrade.

🔐 Essential WordPress Security Tips for 2025 (Free & Simple)

Securing your WordPress website doesn’t require expensive tools. You can protect 90% of your site by following basic practices. These are easy steps every website owner should follow:

1. Enable SSL (HTTPS)

Most hosting providers offer a free SSL certificate.
It protects login details, prevents data theft, and is required by Google for SEO.

2. Keep Everything Updated

Always update:

• WordPress core
• Themes
• Plugins

Most hacks happen due to outdated software.

3. Remove Unused Plugins & Themes

Even inactive plugins can be a security risk.
Delete anything you don’t actively use. Delete the themes also, if you require you can install them again

4. Use Strong Passwords + Two-Factor Authentication

A secure password and 2FA can stop almost all brute-force attacks.

5. Take Daily or Weekly Backups

Backups save you from unexpected errors and malware disasters. Some hosting providers give free daily or weekly backups for long term plans.

6. Limit Login Attempts

Helps block bots and brute-force attempts.

7. Disable XML-RPC (If not required)

Reduces multiple attack surface points.

⚙️ Daily, Weekly & Monthly Security Routine (Simple Checklist)

Daily

• Open your homepage and check if it loads normally
• Monitor any login alerts
• Keep an eye on sudden slow loading

Weekly

• Update plugins, themes, and WordPress
