A firewall acts as a gatekeeper, monitoring incoming and outgoing network traffic, but it cannot "see" inside files to detect hidden malware. Antivirus software acts as the inspector that scans the actual content of your files and monitors system behavior to block viruses, ransomware, and spyware that may bypass firewall filters.

While older, poorly optimized software could impact performance, modern antivirus solutions are designed to be "lightweight." By utilizing cloud-based processing and "autopilot" modes, they minimize CPU usage so you can work, stream, and game without noticing the security software running in the background.

Cyberthreats evolve daily; therefore, your security software must be up-to-date to recognize the latest "signatures" of new malware. Renewing your subscription annually ensures you have access to the latest threat intelligence and real-time protection updates, preventing your device from becoming vulnerable to emerging exploits.
