"The service has been looking for malicious apps in Market for a while now, and between the first and second halves of 2011, we saw a 40% decrease in the number of potentially-malicious downloads from Android Market." I'm not sure how to read this. They detect an App is malware and leave it in the market? Or they didn't detect it until after it had been downloaded many times? The former is unfathomable while the latter indicates a gaping hole in the system. "This drop occurred at the same time that companies who market and sell anti-malware and security software have been reporting that malicious applications are on the rise." Don't believe all the charts showing a malware explosion on Android, they have a conflict of interest. We at the Official Google Android Blog continue our 100% neutrality however. "While it’s not possible to prevent bad people from building malware, the most important measurement is whether those bad applications are being installed from Android Market" Not if you're going to advertise side-loading as a feature the competition lacks.
