Core Shields
Access this feature from: Protection ▸ Core Shields
The Core Shields screen allows you to enable or disable the main protection components in Avast Antivirus.
By default, all Core Shields are enabled to provide optimal protection. To disable a shield, click the ON slider and select a time duration, then click Yes to confirm the action. The slider then switches to OFF. We strongly recommend you keep all Core Shields enabled and only make configuration changes if you have an advanced understanding of malware protection principles.

It monitors all processes on your PC in real-time for suspicious behavior that may indicate the presence of malicious code. Behavior Shield works by detecting and blocking suspicious files based on their similarity to other known threats, even if the files are not yet added to the virus definitions database.
