I recently purchased an Amazon Fire 7, even though I admit I am totally ignorant on the subject (It was just too cheap to pass up). I have managed to navigate around the device, and download apps, connect to my e:mail account and the like, but I am wondering about the security of this tablet. On my PC's, I routinely turn on my firewall and set up spyware and virus protection. Is this not the case with tablets? I don't have a smartphone and I'm not familiar with the operating system of this device. How secure are they? Are there steps I should be taking to protect my information? I would appreciate any and all advice. Thanks.
