It also protects you from Trojans which pose as legitimate software, but infect your device with malware. Web shield also detects phishing websites that attempt to steal personal data.
Avira provides a variety of settings that you can alter to modify the way that avast web shield functions. You can, for instance, change the sensitivity setting, which controls the aggressiveness that avast Web Shield scans data when you connect to internet. You can also activate and disable HTTPS scanning as well as script scanning and block botnets. You can also create an exclusions list to block certain programs being detected by web shield.
If avast web shield detects malware, potentially unwanted program (PUP) or any suspicious file on your computer, it will try to fix it in the first place. If it isn’t repairable it will be moved by avast to file to Quarantine and inform you of its discovery. You can also choose an action for avast to take if it detects a virus.
You can add a site or application that you are sure is safe to the exceptions, so it won’t be blocked again. You can do this by clicking on the Real-Time Shields tab and then selecting the Web Shield (or File Shield) option from the list. The process for adding an app or website to the list of exceptions differs slightly for the Avast Security and Avast One apps.
