Malwarebytes

Malwarebytes protects computers and mobile devices from malware, ransomware, phishing, and other online threats. It works alongside or as a replacement for traditional antivirus software, scanning for threats that other tools may miss.

How it works

Malwarebytes runs in the background on your device, scanning files and web traffic in real time. It detects and removes malware, blocks malicious websites, and stops phishing attempts before they reach you. On-demand scans let you check your system any time, and scheduled scans run automatically.

The free version handles on-demand scanning and removal. Paid plans add real-time protection, a VPN, and coverage for multiple devices.

Who is it for

Malwarebytes is a good fit for anyone who wants straightforward device protection without the complexity of a full security suite. It is popular with people who want a simpler alternative to Norton or McAfee, and with users who want a second layer of protection alongside their existing antivirus.
