I was using AVG Free Antivirus; but, I was getting too many 'AVG messages, of which websites were safe. So; I switched to Bitdefender, which is preferred by PC magazine, for top free antivirus software.

Windows 10 comes with MSIE Internet Explorer 11; but, I also I use the latest edition of Google Chrome 2016, that uses a microphone; so, you can talk to it, and then, it finds the web sites when your web surfing. Get Google Chrome, download website.
