Norton and Malwarebytes serve different purposes in cybersecurity. Malwarebytes Free is an on-demand scanner that lacks real-time protection, while Malwarebytes Premium offers a lightweight app with minimal settings. Norton provides comprehensive protection with a resident scanner included in all tiers. Norton excels in real-time protection, lab test scores, and features such as a firewall and parental controls, while Malwarebytes is effective at removing existing infections and has a free tier. Users can run Norton and Malwarebytes together, but it's recommended to use only one resident scanner to avoid conflicts. Malwarebytes maintains consistent pricing, while Norton has higher renewal costs. Malwarebytes is known for its user-friendly interface and quick installation, whereas Norton offers 24/7 support. In tests, both products effectively detected and removed threats, but Malwarebytes performed better in cleanup tasks.
