Malwarebytes Review 2026: 98% Detection at $44.99/yr (Worth It?)

Malwarebytes built its reputation doing one thing exceptionally well: removing malware that other antivirus software missed. Since 2006, it has been the tool IT professionals reach for when a machine is compromised. But can specialized malware removal translate into everyday protection?

We spent 90 days testing Malwarebytes Premium alongside traditional antivirus solutions to answer a critical question: should Malwarebytes replace your antivirus, or complement it?

Quick Verdict

Malwarebytes Premium is not designed to replace comprehensive security suites like Norton or Bitdefender. Instead, it excels as a specialized second layer of protection that catches threats your primary antivirus might miss. The lightweight scanner, excellent remediation capabilities, and free Browser Guard extension make it valuable for security-conscious users.

Bottom line: If you already have a primary antivirus and want an additional safety net, Malwarebytes is the best second-layer protection available. If you need an all-in-one security solution, look elsewhere.

What Is Malwarebytes?

Malwarebytes takes a different approach than traditional antivirus software. Rather than trying to be everything to everyone, it focuses on specialized threat hunting and remediation:

• Signature-less detection using behavioral analysis and machine learning
• Real-time protection against malware, ransomware, and exploits (Premium only)
• Browser Guard free extension blocking ads, trackers, and malicious sites
• Rootkit scanning that goes deeper than typical antivirus
• Exploit protection for vulnerable applications
• Ransomware rollback to recover encrypted files (Premium only)

What Malwarebytes does not include:

• No VPN
• No password manager
• No cloud backup
• No parental controls
• No identity monitoring
• No firewall

This focused approach is intentional. Malwarebytes believes that doing fewer things exceptionally well beats doing many things adequately.

Malware Detection and Protection

Malwarebytes uses a different detection methodology than traditional antivirus, which makes direct comparisons tricky. Here is what independent testing reveals:

AV-TEST Results (October 2025)

Category	Score	Industry Average
Protection	5.5/6	5.6/6
Performance	6/6	5.5/6
Usability	6/6	5.7/6

Malwarebytes achieved a 98.2% protection rate against zero-day malware in the most recent testing period. For widespread malware detected in the four weeks prior to testing, detection reached 99.5%.

AV-Comparatives Results (July-October 2025)

• Real-World Protection: 97.8% malware blocked
• False Positives: 2 (very low)
• Rating: Advanced (second tier)

These numbers put Malwarebytes slightly behind top performers like Norton (100%) and Bitdefender (99.9%), but the gap is smaller than it appears in practice.

Why the Numbers Do Not Tell the Whole Story

Traditional antivirus testing measures detection of known threat samples. Malwarebytes specializes in catching threats that traditional antivirus misses - by definition, those are harder to test for.

During our 90-day test, Malwarebytes caught:

• 3 potentially unwanted programs (PUPs) that Windows Defender missed
• 1 browser hijacker that slipped past Norton
• 8 malicious advertisements blocked by Browser Guard
• 0 ransomware attacks (tested with simulated samples)

Real-Time Protection Features

Malwarebytes Premium includes four layers of real-time protection:

Web Protection

Blocks connections to malicious websites, phishing pages, and scam domains before your browser loads them. During our testing, Web Protection blocked 47 potentially dangerous URLs across general browsing and email link testing.

Malware Protection

Monitors file activity and blocks malware before it can execute. Uses behavioral analysis to detect threats that signature-based detection might miss. Particularly effective against zero-day threats and polymorphic malware that constantly changes its code.

Ransomware Protection

Specifically designed to detect and stop ransomware attacks. Monitors for suspicious encryption behavior and can roll back encrypted files to their pre-attack state. We tested this with controlled ransomware samples - Malwarebytes stopped all attempts and successfully recovered test files.

Exploit Protection

Shields vulnerable applications (browsers, document readers, media players) from exploit attacks. Blocks memory-based attacks, drive-by downloads, and weaponized documents. Particularly valuable if you cannot always update software immediately.

Browser Guard: The Free Power Tool

Browser Guard is a free browser extension that deserves its own section. It works independently of Malwarebytes Premium and provides substantial protection at no cost:

What Browser Guard Blocks

• Malware and phishing: Stops malicious downloads and fake login pages
• Scams: Blocks tech support scams, fake alerts, and social engineering
• Trackers: Removes tracking scripts that follow you across sites
• Ads: Blocks intrusive advertisements (optional)
• Clickbait: Filters misleading content from news feeds

Browser Guard Performance

Metric	Result
Malicious URLs blocked	99.1%
Phishing sites blocked	98.4%
Ads blocked	94%
Trackers blocked	96%
Page load impact	+3% average

Browser Guard adds minimal overhead while providing meaningful protection. The ad blocking alone can speed up page loads enough to offset the extension’s footprint.

Supported Browsers

• Google Chrome
• Mozilla Firefox
• Microsoft Edge
• Safari (macOS only)

System Performance Impact

This is where Malwarebytes truly shines. It was designed from the ground up to be lightweight, and it delivers:

AV-Comparatives Performance Test (September 2025)

Malwarebytes earned an Impact Score of 2.1 - one of the lowest (best) scores in the entire test. For context:

Security Software	Impact Score
Malwarebytes	2.1
Kaspersky	2.8
Norton	3.8
Bitdefender	4.2
McAfee	8.5

Lower scores indicate less system impact. Malwarebytes is measurably lighter than major competitors.

Our Real-World Testing

We tested Malwarebytes Premium on three systems:

Gaming PC (RTX 4070, Ryzen 7 7800X3D, 32GB RAM):

• Full system scan: 4 minutes
• CPU usage during scan: 8-12%
• Gaming impact: Undetectable

Work Laptop (Intel i7-1260P, 16GB RAM):

• Full system scan: 9 minutes
• CPU usage during scan: 15-22%
• No noticeable slowdown during normal work

Older Desktop (Intel i5-8400, 8GB RAM):

• Full system scan: 12 minutes
• CPU usage during scan: 18-25%
• Minimal impact even during scans

Malwarebytes consistently completed scans faster than competitors while using fewer resources. On older hardware especially, this difference is noticeable.

Why It Matters

Heavy security software creates a frustrating paradox: protection that slows you down gets disabled. Malwarebytes stays out of your way, which means it stays running. That matters more than benchmark scores.

Frequently Asked Questions

Can Malwarebytes replace traditional antivirus?

Technically yes, but it is not recommended for most users. Malwarebytes achieves 98% detection rates, which means roughly 2 out of 100 threats might slip through. For maximum protection, pair Malwarebytes with Windows Defender or another traditional antivirus. Malwarebytes is designed for this layered approach and will not conflict with other security software.

Does Malwarebytes work with Windows Defender?

Yes, and this is actually the recommended configuration. Malwarebytes automatically registers with Windows Security Center but continues running alongside Windows Defender rather than replacing it. This gives you Microsoft’s broad malware detection plus Malwarebytes’ specialized threat hunting.

Is Malwarebytes free version good enough?

The free version is excellent for what it does - scanning and removing existing infections. However, it does not provide real-time protection, meaning it cannot stop malware before it infects your system. Think of it as a remediation tool rather than a prevention tool. For continuous protection, Premium is necessary.

How does Browser Guard compare to uBlock Origin?

Both block ads and trackers effectively. Browser Guard adds malware and phishing protection that pure ad blockers lack. Many users run both - uBlock Origin for comprehensive ad blocking and Browser Guard for security-focused blocking. They work together without conflicts.

Why are Malwarebytes detection rates lower than competitors?

Malwarebytes uses behavioral detection rather than signature-based detection, which tests differently in lab environments. Traditional testing favors known threat samples where signature-based detection excels. Malwarebytes’ strength is catching novel threats that evade traditional detection - something lab tests cannot easily measure.

Does Malwarebytes slow down gaming?

No. In our testing, Malwarebytes had no measurable impact on frame rates or game performance. Its lightweight design specifically avoids the resource conflicts that make gamers disable security software. You can game with Malwarebytes running without concern.

Is Malwarebytes Premium + Privacy VPN worth it?

For most users, no. The bundled VPN is functional but basic compared to dedicated VPN services like NordVPN or ExpressVPN. If you need both malware protection and VPN, you are likely better off buying Malwarebytes Premium separately and adding a dedicated VPN. The bundle only makes sense if you want simplicity over optimization.

How do I use Malwarebytes with another antivirus?

Simply install both. Malwarebytes automatically detects other security software and runs in compatibility mode. Both programs provide real-time protection without conflicts. If you experience any issues, Malwarebytes support can help configure the optimal setup for your specific combination.

Final Verdict

Malwarebytes occupies a unique position in the security software market. It is not trying to be the most feature-rich solution or achieve perfect detection scores. Instead, it does one thing exceptionally well: catching and removing malware that other security software misses.

The 98% detection rate sounds concerning until you understand the context. Malwarebytes is designed to work alongside traditional antivirus, not replace it. When paired with Windows Defender or a comprehensive suite like Norton, you get layered protection that covers each solution’s blind spots.

Where Malwarebytes truly excels:

• Performance: The lightest major security software available, period
• Remediation: The tool IT professionals trust for cleaning infected machines
• Browser Guard: Free protection that rivals paid competitors
• Transparency: No renewal price increases or hidden fees

Where it falls short:

• Feature set: No VPN, backup, parental controls, or identity monitoring
• Detection rate: Slightly behind top-tier competitors in lab testing
• Support: Limited to email and knowledge base

For security-conscious users who want a specialized second layer of protection, Malwarebytes is the best option available. For users who want a single, comprehensive security solution, Norton 360 or Bitdefender Total Security are better choices.

Our Rating: 4.3/5
