Android security - a Q&A with Google's Adrian Ludwig

Very interesting interview with Adrian Ludwig, lead engineer for Android security at Google. There are a lot of fascinating answers to quote here, and I'm going for this one - do you need antivirus crap on your Android phone?In 2014, according to Verify Apps data collected by Google and ignoring rooting apps that were intentionally installed by users, fewer than 0.15 percent of Applications installed from outside of Google Play to U.S. English devices were classified as Potentially Harmful Applications. Given the built-in protection provided by Verify Apps and the low frequency of occurrence of installation of PHAs, the potential security benefit of an additional security solution is very small.I - and many others - have been saying this for ages, but let me just repeat it: do not install third-party security solutions on your Android phone. They are useless resource hogs that provide no additional security, and are built by scammy, untrustworthy, and needlessly alarmist software peddlers.That being said, it'd be great if Google released more information about these background security tools in Android - more specifically, numbers, numbers, numbers.
