In a recent post we mentioned that purchasing preloaded devices can pose a serious security risk to not just your Android device, but also other hardware that is connected to your home's network.
Today, we wanted to expand on that a little, and get into the details of what can happen, and how to avoid it.
We'll start off with a nice infographic to give you an overall feel for the current situation with one particular area of malware, though many of the warnings and conclusions apply throughout the malicious code area.

If that seems like to much scrolling, the ultra compressed version is simple to remember:
Don't buy "fully-loaded" Chinese devices from unknown sellers and don't use untrusted applications!

See Symantec's report here for more information regarding the need to consider security on any digital device. There are a couple of Android specific sections you can click on in the index to jump straight to the relevant paragraphs.
So, you are now aware of the threats you may come across. Forewarned is forearmed, after all. But, how about actually stopping malicious code from executing on your Android set top box? There are a bewildering number of applications available to defend your digital device - we've boiled it down to the major players, those that have been in the business a while and have impressive research facilities.
Don't install more than one unless the author expressly recommends it (for example if you have one Anti-Malware and one Anti-Virus application with no overlap).
Once you have protection in place, consider the other aspects of security. If you regularly install applications without using Google's Play Store or DroidBOX's own DroidBOX Market, then make sure the APK file has been checked before opening it.
If adverts pop up, masquerading as genuine System Alerts (Warning: Your device is underperforming!) never, EVER click on them. Look for an X to click on to close the advert, or press the Return arrow button on your remote control. If that doesn't work, press the home button.

If you come to this post with an already infected device, and the applications linked to in our Antivirus Malware Protection For Android Devices post, most can be removed with a factory reset, please see https://droidbox.co.uk/how-to/accessing-your-droidboxs-recovery-menu/ for details on how to do this with DroidBOX set top boxes. You will lose your data and settings, but do install an antivirus application again afterwards, and make sure the infection has been removed.
