Avast web shield actively tests the information that moves when you browse the internet and stops any potential infections in real-time. This shields you from ransomware which blocks your files and requires payment to unlock them and Trojans, which masquerade as legitimate software, but infuse malware onto your device. Web shield also detects phishing websites that attempt to steal your personal information.
Avira offers a variety of settings to customize the way avast Web Shield operates. For example you can alter the sensitivity level, which controls how much avast’s web shield scans the data when you connect to the internet. You can also disable or enable HTTPS scanning or script scanning. It is also possible to block botnet attacks. You can also create a list of exclusions to prevent certain programs from being detected by the web shield.
If avast’s web-based security detects malware, potentially unwanted program (PUP), or suspicious files on your computer it will attempt to fix it before you do. If it’s not possible to repair then avast will transfer the file to Quarantine and notify you of its detection. You can also choose a default action avast takes when a threat has been detected.
You can add a website or an application which you are certain is secure to the exceptions so that it isn’t blocked again. This can be done by clicking the Real-Time Shields tab and then selecting the Web Shield or File Shield item in the list. The Avast Security app and Avast One app have slightly different methods for adding websites or apps to the list of exceptions.
