Web Shield protects your system from threats while browsing the web. It also prevents malicious scripts from running, even when you are offline. In Web Shield, you can enable and configure web, HTTPS, and script scanning.
Web Shield Settings
Web Shield actively scans data that is transferred when you browse the internet to prevent malware from being downloaded and run on your PC. To enable and configure Web Shield, go to Menu > Settings > Protection >
The following configuration options are available:
EnableWeb Shield: Turn the shield on or off
- Enable HTTPS scanning: Specify if Web Shield should scan encrypted websites
- Enable QUIC/HTTP3 scanning: Specify if Web Shield should scan communications sent and received via Google's QUIC protocol
- Enable WebSocket protocol scanning: Specify if Web Shield should scan traffic used by web apps
- Protect against botnets: Specify if Web Shield should detect and block botnets from connecting to malicious servers
- Enable Script scanning: Specify if Web Shield should block malicious scripts from applications and websites. This includes remote threats from the web and outside sources, and local threats saved to disk or in the browser cache. Script scanning can also detect and block malicious scripts that come from HTTPS (encrypted) connections
- Enable site blocking: Allows you to block access to specific websites added to the list via the Show Blocked Website dialog box (see Adding Blocked Sites below for more information)
- Generate report file: Specify if Web Shield should automatically generate report files and save them on your device
Viewing, Adding, and Removing Blocked Websites
You can specify the websites you want to block by clicking the Show Blocked Websites button under the Enable site blocking setting, then selecting + Add Website and typing in the website URL.
Any websites you add or have previously added to the list will be visible in this dialog. If needed, you can remove a blocked website from the list by clicking the trash icon next to the URL and confirming the removal.
When an infected website is accessed, Web Shield will display a dialog directly in your browser, informing you about the detected threat and offering the option of scanning your device. Selecting Scan your PC will open your Antivirus client and start the scan.
Currently, only Chrome and Firefox browsers are supported.
The detection ID at the bottom of the dialog can be copied and sent to Avast Support for analysis.
