This is probably a noob question, but how safe is using FON hotspots? I know it's probably not a good idea to check my bank account, or do anything envolving money transactions, when I'm on FON hotspots, or any other open access WiFi, by the way. But other than that, should I avoid using FON for the other day to day stuff? I don't mean checking the weather or reading the news... I'm talking about something more like checking emails, logging in to forums, logging in to webhosts, etc... As long as it's an https connection, am I secure? Or should I always use a VPN when on a WiFi hotspot(FON or not)? Are free VPN any good? I think I know the answer to that one, but anyway I would like to hear from you on this, as there might be some exceptions. What if I'm using an android device, should I also be worried about security and use a VPN? I know that many of you believe that one should always use a VPN, even when using my home connection, but at this moment my main objective is to find out if it's secure to use a FON hotspot, and how can I make its usage more secure. When accessing FON using my PC, I usually use a virtual machine running Ubuntu, but from time to time I also use it while running windows. Is running windows riskier? Thanks in advance.
