Google has made some beneficial recent changes as noted below:
QUOTE: Google has made a number of changes to its Android Play Store ecosystem recently. Part of the reason is that Mountain View has been copping lots of flak for the prevalence of malware in unofficial application markets, often in pirated apps. That’s a trifle unfair, since one of the attractions of Android over Apple’s iOS is that it’s actually possible to shop “off-market” if you wish. Sure, there’s a greater risk of shooting yourself in the foot if you do, but you’re not forced to live dangerously, and even if you do go outside the Play Store, a little caution goes a long way towards keeping you safe. More realistically, however, Google has been criticized for the appearance of malicious apps in its own Play Store.
