Avast Web Shield actively tests information that is moving through the internet and blocks possible infections in real time. It guards against ransomware which blocks your files and demands a payment to unlock them and Trojans disguised as legitimate software, but actually inject malware onto your device. Web shield also identifies phishing websites that attempt to steal your personal data.
Avira offers official site multiple settings that you can set to alter the way that avast Web Shield functions. For instance, you can change the sensitivity level, which determines the degree to which avast web shield examines data when you connect to the internet. You can also turn off or on HTTPS scanning or script scanning. It is also possible to stop botnet attacks. You can also make an exclusion list to prevent certain programs from being detected by web shield.
If avast’s web shield detects malware, potentially unwanted programs (PUP), or suspicious files on your PC, it will try to fix it in the first place. If the file is unable to be repaired it will be moved to Quarantine. You will also be notified. You can also create a default option that avast will perform whenever a threat is detected.
You can add a website or application that you are confident is safe to the exceptions so it will not be blocked again. This can be done by selecting the Real-Time Shields tab, and then selecting the Web Shield or File Shield item from the list. The Avast Security app and Avast One app have slightly different methods for adding apps or websites to the list of exceptions.
