- Web Shield: The Web Shield monitors and filters all HTTP traffic coming from web sites on the Internet. Connections from your web browser are redirected to the Web Shield module. The Web Shield in turn connects to the requested web server and while downloading the content, it simultaneously scans it for viruses and Trojans.
