Rarely, both Avast’s real-time shields and scheduled scans detect positives against items that are in fact not a threat to the security of your computer. You can, however, add folders, websites or applications that you deem as trustworthy to an exclusions list, thus preventing Avast from producing false positives. You can also make Avast bypass folders during manual scans by adding them to a temporary exclusions list.

Permanent Exclusions

Step 1

Open your Avast Free Antivirus or Avast Internet Security installation.

Step 2

Click "Settings," and then click "Antivirus."

Step 3

Scroll down to the section named “Exclusions.”

Step 4

Click the “File Paths” tab and use “Browse” to select folders that you need to exclude from Avast. To exclude a website, click the “URLs” tab and enter the URL of the website into the field labeled “Enter Address.” To prevent an application from getting flagged by Avast’s DeepScreen and Hardened Mode security modules, click the “DeepScreen” and “Hardened Mode” tabs and use “Browse” to select the executable file of the application.

Step 5

Click “Add” to insert the folder, URL or application to Avast’s exclusions list.

Temporary Exclusions

Step 1

Click "Scan" on the Avast Free Antivirus or Avast Internet Security main window. Next, click “Create Custom Scan” on the lower right of the window.

Step 2

Click “Exclusions” on the Scan Settings pop-up window.

Step 3

Use “Browse” to select folders that you need to exclude from scanning.

Step 4

Click “Add,” and then click “OK.”
