Proxy Tester is a proxy list tester and then it generates a wpad.dat file you can use for your browser based on working servers. wpad.dat file selects a random proxy server from the list of provided working proxy servers with each connection request.
Viralator enhances your network's squid proxy server with a virus scanner. Before a user can download a file, the proxy passes the file to the Viralator script which, in turn, uses a virus scanner to scan, disinfect, or delete the download.
