Avast web shield continuously tests the information that is transferred when you surf the internet and stops any infections that could be a threat in real-time. It protects you from ransomware, which locks your files and demands payment to unlock them and Trojans that disguise themselves as legitimate software but inject malware onto your device. Web shield also detects phishing sites which attempt to steal your personal information.

Avira provides multiple settings to customize the way avast Web shield functions. You can, for instance alter the sensitivity setting that controls the intensity of the way avast Web Shield scans data when connecting to internet. You can also enable or disable HTTPS scanning as well as script scanning, and block botnets. You can also create an exclusion list in order to avoid certain programs being detected by web shield.

If the avast web security detects malware, potentially unwanted programs (PUP) or a suspicious files on your computer it will attempt to repair it first. If it isn’t repairable, avast will move the file to Quarantine and inform you of its discovery. You can also select a default action for avast to take if it detects a virus.

If a website or an app that you believe to be safe is blocked by avast, you can add it to the exceptions list so that it won’t be blocked again. This can be done by selecting the Real-Time Shields tab, and then selecting the Web Shield or File Shield option in the list. The Avast Security app and Avast One app have distinct methods of adding websites or apps to the exceptions lists.
