It goes beyond traditional antivirus with AI-powered scans, real-time threat blocking, and a Browser Guard extension that catches phishing sites and malicious ads before they load. Malwarebytes has been around since 2008 and runs on Windows 7 through 11, plus Mac, Android, and iOS.

Common Issues and Fixes
Scans are running slowly
Switch to Hyper Scan mode for a faster check. Hyper Scan focuses on active threats and memory instead of scanning every file on your drive. Full scans are still recommended weekly.
The app will not open or is crashing
Download the latest installer from the official site and reinstall. Your subscription and settings are tied to your account, so you will not lose anything.
Web Protection keeps turning off
Go to Real-Time Protection in the settings panel and toggle Web Protection back on. If it keeps disabling itself, check if another security tool is conflicting. Malwarebytes works alongside Windows Defender, but some third-party antivirus tools may cause conflicts.

Frequently Asked Questions
Is Malwarebytes Premium better than free antivirus?
For most users, yes. Free antivirus tools scan for threats but do not block them in real time. Malwarebytes Premium runs in the background and actively stops malware, ransomware, and phishing attacks before they reach your PC. It also includes Browser Guard, which blocks malicious ads and scam websites.
Does it slow down my PC?
No. Malwarebytes is built to be lightweight and uses around 50% less CPU than many competing security tools. It runs quietly in the background and you should not notice any impact during browsing, gaming, or normal work.
Can I try it before buying?
Yes. Every install comes with a 14-day free trial of Premium features. After the trial ends, you can either subscribe or keep using the free version, which still allows manual scans but loses real-time protection.
Does it work alongside Windows Defender?
Yes. Malwarebytes is designed to run alongside Windows Defender without conflicts. Many users keep both active. Defender handles baseline Windows security while Malwarebytes adds real-time malware blocking, browser protection, and AI-driven threat detection.
What platforms does it support?
Malwarebytes works on Windows 7 through 11, macOS, Android, and iOS. Multi-device plans let you protect up to 5 devices across different platforms with a single subscription.
Is there a money-back guarantee?
Yes. Malwarebytes offers a 60-day money-back guarantee on all Premium plans. If you are not satisfied, you can request a full refund within that period.
