Avast Web Shield constantly tests information that is moving through the internet and stops any potential threats in real-time. This protects you against ransomware which locks your files and requires a payment in order to unlock them. It also protects you from Trojans that claim to be legitimate software, but infect your device with malware. Web shield also identifies phishing websites which attempt to steal your personal information.
Avira has a variety of settings you can configure to customize how avast web shield works. For example you can alter the sensitivity level, which regulates the degree to which avast web shield scans the data when you connect to the internet. You can also activate and 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 identified by web shield.
If avast finds malware or potentially unwanted programs on your computer, it will attempt to repair the file first. If the file can’t be repaired it will be transferred to Quarantine. You will also receive a notification. You can also create a default option that avast will take when a threat is detected.
You can add a web page or app that you are confident is safe to the exceptions, so it won’t be blocked in the future. This can be done by clicking on the Real-Time Shields Tab, and then selecting either the Web Shield (or File Shield) option from the list. The Avast Security app and Avast One app have slightly different methods for adding websites or apps to the exceptions lists.
