Seriously?
Yeah, to this day, I never disable UAC on Windows unless it is absolutely required by a business application that I am required to install. I cancel installs that ask for a promiscuous level of permissions. I also do not install every stupid app that catches my eye. I look for an app when I ha e a need and then I look for a well-known, trusted vendor.
As to the Google Play Store, the problem is that Google wants millions of apps on offer, so they abdicate the basic responsibilty a reseller has, to choose decent products to sell their customers. How much nicer it would be if Gooogle picked a handful of products, say a few thousand, of which they thought highly, from vendors with whom they had an ongoing, established relationship.
