Google has announced an upgrade to the Play Protect malware defense feature in the Android system to better detect malicious software that uses artificial intelligence and other methods to evade detection. This enhancement will help in better defending against so-called "polymorphic malware," which is difficult to detect with Google's current systems. Despite the potential ineffectiveness of the Google Play store in blocking Android malware, its security remains superior to unofficial channels. Google states that it scans over 125 billion apps daily to prevent the spread of malware. This initiative aids in identifying malware that changes characteristics after being sideloaded from unofficial channels.
