There are some people who think Android is like the Wild West. They think the sheriff, Google, is out-of-town and everyone is free to do as they please. This is obviously not true. Google has advanced security tools with many layers of protection. The 0.001% of apps that do make it pass Google’s security have to make it through 7 layers of security. If the user doesn’t have unknown sources enabled, like most average users don’t, the app won’t even make it past the second level. Android is not the wild west, but it’s not Apple’s walled garden either. Google will let anyone upload an app to the Play Store, but that doesn’t mean they will let it infect your device. They have your back. All of this fear mongering around Android malware has created opportunities to make some easy money. A lot of people are more than willing to shell out a few bucks if they think it will protect them. There are some really nice security apps available, but most of the ones that cost money aren't worth it.
