scanner vs full protection

Scanner vs. full protection: What do I need?

While the online scanner is perfect for immediate malware removal, it’s only one part of a broader security solution. For ongoing, real-time protection that includes a robust firewall, a secure password manager, and continuous threat monitoring, explore our full protection trial. Think of the scanner as your first line of defense—and the full trial as the long-term safeguard for your digital life.
