Most of us rarely takes serious safety measures and sometimes things go beyond a simple virus, therefore, always its advisable that when we are surfing in public places, a supported VPN connections remain anonymous and a better choice.
In case, if you use Firefox, I recommend Cocoon A VPN proxy service to help us navigate safely from our computer when we are active in public networks.

Cocoon service is not new, but previously only offered by fees, now it becomes free. With this extension we will be able to surf anonymously the web without being contaminated by malware, do not leave traces, and better yet, avoid ads by tracking, in addition to maintaining our mail anonymously perfectly protected.
