What is Avast Web Shield?

Web shield is part of the avast anti-virus software that scans your data when you browse online. This safeguards your computer from malware. Web shield blocks websites and prevents hackers from using your computer as a host when hacking into other computers. It can block harmful software and notify the community about it.

The avast web shield uses advanced technology to block and detect the most recent threats. It works in real-time, scanning files and programs as they’re opened or downloaded. It also detects ransomware, which locks the files on your device, and requires payment to unlock them. It can also identify trojans that pose as legitimate software but insert malware onto your system.

Avast offers multi-platform protection against malware, viruses and spyware. It also protects you from ransomware, scams, and trojans. It is available for Microsoft Windows, macOS, Android and iOS. The company offers both the free version for each platform as well as an upgrade version with more features.

When Avast detects a threat it immediately warns you about the threat and alerts its community of users to the danger. If a malicious application is downloaded and runs on your device, it can damage the operating system, corrupt files or even steal your personal data. If you wish to use a website or application that Avast has blocked, you can add it to your exclusions list. You can also disable Web Shield and File Shield to allow safe websites and applications to run on your device.
