Malware attacks are on the rise, targeting websites of all types—from personal blogs to enterprise platforms, thus strong malware protection is no longer optional—it’s essential. These threats can inject malicious scripts, steal sensitive data, and seriously damage your reputation and customer trust. Whether you’re running a small online store or managing a high-traffic business site, the best defense is prevention.
This guide outlines proven best practices for preventing malware attacks and keeping your website secure in an increasingly dangerous digital world.
Keep Software Updated to Patch Vulnerabilities
Outdated software is one of the leading causes of malware infections. Developers release updates not just for new features but to fix security flaws that hackers actively exploit.
- Update your WordPress core as soon as new versions are available.
- Apply updates to all plugins and themes regularly.
- Remove unused plugins or themes—they add risk with no benefit.
Pro Tip: Use a managed update plugin or WordPress maintenance service to automate these updates while testing for compatibility.
Use a Web Application Firewall (WAF) for Real-Time Protection
Implementing a Web Application Firewall (WAF) is one of the most effective forms of malware protection, helping to block known malicious IPs before they can interact with your website.
- Best Tools for Malware Protection in WordPress are: Cloudflare WAF, Sucuri Firewall, and Astra Security.
- These services protect against SQL injection, cross-site scripting (XSS), brute force attempts, and more.
Why it matters: WAFs analyze behavior and traffic patterns, blocking threats that traditional security plugins may miss.
Enforce Strong Passwords and Multi-Factor Authentication (MFA)
Weak credentials are low-hanging fruit for hackers. A strong password policy significantly reduces unauthorized access.
- Require complex, unique passwords for all users.
- Force password resets every 90 days.
- Enable MFA for all admin-level accounts.
Use tools like:
- Google Authenticator
- Duo Security
- Wordfence Login Security
Regularly Scan for Malware Infections
Even the best defenses aren’t impenetrable. Frequent scanning helps detect infections before they spread or are flagged by Google.
Schedule automatic malware scans with plugins like:
- Wordfence
- MalCare
- iThemes Security
Perform manual audits of core files, themes, and user activity.
Scan server directories for unexpected PHP files or modified timestamps.
Early detection saves time, reputation, and recovery costs.
Limit Access and File Permissions
Malware often spreads by exploiting over-permissioned user roles or unsecured file structures.
Follow the principle of least privilege:
- Only give users the access they need.
- Disable default admin accounts and unused roles.
Secure sensitive files and directories:
- Set file permissions to 644 and folders to 755.
- Restrict access to /wp-config.php, .htaccess, and /wp-admin/.
Consider using server-side protection rules via .htaccess or NGINX configurations.
Backup Your Website Frequently and Securely
Regular backups and real-time activity monitoring are foundational components of any solid malware protection strategy.
Automate daily or weekly backups with tools like:
- UpdraftPlus
- WPVivid
- BlogVault
Store backups securely:
- Use offsite cloud storage (Google Drive, Dropbox, Amazon S3).
- Encrypt backup files.
Backups should include your entire site: WordPress files and your database.
Enable HTTPS with an SSL Certificate
Encrypting communication between the browser and your server protects against data interception and malware injections.
- Install a free SSL certificate from Let’s Encrypt or get one through your hosting provider.
- Ensure all internal links, scripts, and stylesheets are served via HTTPS.
Modern browsers flag sites without HTTPS as “Not Secure”, which can impact SEO and trust.
Monitor Server Activity for Anomalies
Real-time monitoring can reveal early signs of compromise, such as:
- High CPU usage
- Strange login locations
- Sudden changes to file sizes or database tables
Use monitoring services or plugins to get alerts:
- Sucuri SiteCheck
- ManageWP
- New Relic (for performance and security insights)
Harden Your WordPress Installation Against Malware
Take your protection further by disabling high-risk WordPress functions:
Add the following to wp-config.php:
define('DISALLOW_FILE_EDIT', true);
define('DISALLOW_FILE_MODS', true);
Lock down /wp-admin/ and restrict access by IP.
Protect .htaccess, wp-config.php, and other critical files from public access.
Educate Your Team About Malware Threats
Security is only as strong as its weakest human link.
Train admins and contributors to:
- Recognize phishing emails
- Avoid installing unverified plugins or themes
- Use secure login practices
Establish a response plan for when something goes wrong.
Knowledge is the best defense against social engineering attacks.
