Smartphone Era, you'll see more Adware than viruses thus the harder detection from the lacking Android AV's

Naturally the reason is easy, infect phone, they click ads accidentally when they pop up randomly on the device = Profit. That's why people are so keen to do it. Can imagine how many people don smartphones now opposed to a desktop.

Desktops again are becoming a relatively 'fanboy' device, I have one because I love gaming but the more average users are using Android running tablets and IOS devices. So, you get my mother, whom owns a Smartphone running Android, who has absolutely no idea about the device or the OS, just that it 'plays' apps and she can use Facebook. She is the target for the ads.. as are millions of others.

If the infected App sits in a quarantined like state for days/weeks then suddenly triggers it's even harder to catch out without manually inspecting all apps as you've probably downloaded even more apps since then. They're getting smarter. Infected app installed > Ads pop up > Unistalled - Doesn't cut it anymore. Likely to see App installed > Dormant for X amount of days > You install more apps > Ads pop up > Faf on trying to locate the source.

Even legitimate apps do dodgy stuff to get a click from you. E.G, how many times have you went to click something only to have it move place on the screen? typically an ad cross or a menu that's moved and you've clicked the ad instead. That's deliberate now, it used to be random lag spikes on occasion when loading pages or apps but now developers have purposely done it.
