Avast Web Shield actively tests information on the internet and blocks potential threats in real-time. It protects you from ransomware, that locks your files and demands a payment to unlock them and Trojans disguised as legitimate software, but install malware onto your device. Web shield detects phishing websites which attempt to steal your personal data.
Avira provides multiple settings that you can configure to customize the way avast’s web shield operates. For example you can alter the sensitivity level, which determines how much avast’s web shield examines data when you connect to the internet. You can also turn off or on HTTPS scanning scan, script scanning, and block botnet attacks. You can also create an exclusion list to prevent certain applications from being detected by web shield.
If the avast web security detects malware, potentially unwanted program (PUP) or any suspicious file on your computer it will attempt to fix it in the first place. If the file is not repaired the file will be moved to Quarantine. You will also be notified. You can also select an action that avast is expected to take when a virus is detected.
If a website or app that you know to be safe is blocked by Avast, you can add it to the list of exceptions to ensure it never gets blocked again. You can do this by clicking on the Real-Time Shields Tab and then selecting the Web Shield (or File Shield) item from the list. The Avast Security app and Avast One app have distinct methods of adding websites or apps to the list of exceptions.
