Web shield is a component of the avast antivirus software that scans your data when you surf the web. This shields your computer against malware. Web shield blocks websites and prevents hackers from using your computer as a server for hacking into other computers. It can block unwanted software and inform the community about it.
The avast web shield employs advanced technology to detect and block the latest threats. It works in real-time and scans files and programs as they’re downloaded or opened. It also detects ransomware that locks certain files on your device and demands payment to unlock them. It also detects trojans, which disguise themselves as genuine software and introduce malware to your system.
Avast provides multi-platform protection against spyware, malware, and viruses. It also shields you from ransomware, fraud attacks and trojans. It is available for Microsoft Windows, macOS, Android, and iOS. The company offers the free version for each platform, as well as a paid version that comes with more features.
Avast warns you immediately if it detects a threat and alerts the community of Avast users. If a malicious application is downloaded and then runs on your device, it could cause damage to the operating system, corrupt files, or even steal your personal information. You can add a site or app that Avast blocked to your list of exceptions when you decide to use it. You can also disable Web Shield or File Shield to allow secure websites and apps to run on your device.
