Alcatel-Lucent credited the decline of Android infection rates to moves Google has made, including efforts to eliminate malware-ridden apps from the Google Play e-mart, as well as Android's Verify Apps feature. The latter was introduced in 2012 with Android 4.2, aka Jelly Bean, and has been beefed up since then. Verify Apps scans apps a user wants to download, compares them against a Google database, and when a known malicious app is detected, blocks the download.
Google's intent has been to both clean up Google Play and stymie dangerous downloads from outside sources, like third-party app markets. The decline of Android infection rates and its share of all infections were signs that the strategy has worked, said Alcatel-Lucent.
Microsoft has had a similar protection in place since 2011, when it added an application reputation feature to its Internet Explorer-based SmartScreen technology.
Most of the infections Alcatel-Lucent detected on Windows devices was adware bundled with games and free software.
"The increase in Windows/PC infections can be attributed to the fact that more people are using their phone's data connection to provide Internet access for their devices," Alcatel-Lucent concluded.
Alcatel-Lucent Windows' share of malware infections detected on devices using a mobile network climbed to 80% in June, according to scans by Alcatel-Lucent.
