Avast web shield constantly tests the information that you transfer when you browse the net and stops any infections that could be a threat in real-time. This protects against ransomware, which blocks your files and demands payment to unlock them as well as Trojans that disguise themselves as legitimate software but inject malware onto your device. Web shield also detects sites that are phishing that try to steal your personal information.
Avira provides multiple settings that you can alter to modify the way avast’s web shield operates. You can, for example change the sensitivity setting, which controls the aggressiveness that avast Web Shield scans data every time you connect to internet. You can also turn on and disable HTTPS scanning, as well as script scanning and block botnets. You can also create an exclusion list to prevent certain programs from being detected by web shield.
If avast web shield detects malware, potentially unwanted programs (PUP), or suspicious file on your computer, it will try to fix it in the first place. If it cannot be repaired, avast will move the file to Quarantine and notify you of its detection. You can also select the default action that avast will choose to take if the virus is detected.
If a website or an app that you know to be secure is blocked by avast You can add it to the exceptions list to ensure that it is never 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 procedure for adding an app or website to the exceptions list is different for the Avast Security and Avast One apps.
