Public wi-fi is, indeed, potentially hazardous to your computer health, @sophial. Using encryption or a VPN will go a long way towards protecting your private data.

I dont access email over public wifi; I only use the internet to surf, or apps which are protected. I avoid using financial apps, though, if I can avoid it.

Turning off file sharing is another strong tip.

Thanks for the post! I follow and look forward to your next article.
