I've been thinking about getting a Chromebook. Commercial shows that I don't need antivirus with a Chromebook. But then why is antivirus software available? And do I need a VPN when using public wifi or is that built-in also? I've asked the staff at Best Buy and can't get a straight answer. Google help says to ask the manufacturer, but it's Google who advertises the security of their Chromebooks not the manufacturers. Also does anybody have an email address for Google Chromebook so I can get a straight answer in writing from them? Thank you.
