Avast offers free antivirus software for non-commercial and home users, and a Pro version for commercial users and businesses. The Avast antivirus software protects your computer with several real-time monitoring shields that monitor email, Internet connections and computer files to instantly protect you from potential threats. These real-time shields run silently in the background to monitor for viruses and malware, and can interfere with legitimate operations in rare cases, such as installing new software.
Right-click the Avast Antivirus icon in the notification area of your toolbar. The notification area is on the right side of your toolbar.
Hover over the “Avast Shields Control” entry of the right-click contextual menu. This expands the menu to offer additional options. Click “Disable Permanently” to turn off all Avast protection shields.
Click “Yes” to confirm your action in the Avast warning screen. This confirms that you intended to shut down Avast protection.
