Virus activity has dropped more or less proportionally with the roll out of Windows 10, in my observations. The reasoning I think is two-fold. First, installing Windows 10 surely "fixed" any virus issues for Millions of people. Secondly, Windows 10 IS more secure and has a few things going for it (Blocking downloaded apps, Edge (lack of plugins - get from store, dropping of ActiveX, no more BHO's). Also, many vulnerable applications such as old flash players, Acrobat readers, etc got refreshed or removed per Windows 10 upgrade. Windows is actually 'fairly' secure, it's been the installed applications that have opened vulnerabilities. While Windows 10 CAN be exploited by itself, most of those standalone exploits require the attacker to be on the same network, but I digress.
The narrative that "Computers are going away" and "tablets and phones are taking over", simply does not hold water.

PC Sales are UP in the US, but don't expect a great comeback
PC sales are down 5.2%(Gartner), PC Sales are down 4.5%(IDC)
Worldwide, PC shipments are still on the decline year-over-year. Gartner says shipments have fallen 5.2 percent to 64.3 million, while IDC says 4.5 percent to 62.4 million. Either way, the trend line is down. Both firms attribute the US gains to a strong dollar coupled with the PC upgrade cycle among businesses and government customers.
The tablet market is 100 million units smaller than expected. What happened?
Where have all the tablets gone?
Tablet sales are still shrinking—except for tablets that mimic PCs
Tablet sales down 10.1%, 13.7% - Tablets that mimic PC's, sales are UP (That's Windows, guys!)
At 206.8 million, tablet shipments last year were 10.1 percent down on 2014. The decline in the fourth quarter—which, with the holiday season, accounted for almost a third of the year’s sales—was even more marked, down 13.7 percent on a year earlier, according to market researcher IDC.
IDC: Smartphone shipments flat for the first time; Samsung widens lead over Apple in Q1 2016
This figure is up just 0.2 percent from the 334.3 million units in Q1 2015, marking the smallest year-over-year growth on record. We saw hints of this in yesterday’s Apple earnings report, when the company reported
an iPhone sales drop for the first time. Despite the poor state of the worldwide smartphone market, Samsung continues to dominate. In Q1 2016, the South Korean company once again shipped more smartphones than any other vendor. In fact, Samsung out-shipped the next two smartphone makers — Apple and Huawei — combined.
According to the interwebs there are more than 2 Billion computers in service.
Pew Research says that Desktop and Laptop computers are owned by 73% of US adults while Smartphones are 68% and Tablets at 45%. (April-June, 2015).
So no, the numbers don't really fit the narrative so well. A depressed global economy, longer service use of CPU's and less upgrade moves on the part of consumers are thought to be the main drivers of declining sales, not that people are abandoning their devices in lieu of others (That was the media's 'hair-on-fire' story of 2013-2015).
The market has been saturated with PC's and is now becoming saturated with Tablets and Phones. Nothing grows forever.
It will just be a matter of time, IMO, before Virus work returns as Windows 10 ages and people have time to both make effective viruses/exploits and get infected.
