I have read that some cheap Chinese phones have security issues with embedded malware in the operating system that is sending personal data to servers in China. I have installed Norton and McAfee anti-virus for Android on my phone and both flag up that Google Play is Malware. McAfee lists the Malware as Artemis!f1b8b152f145. Is this true Malware or a false positive flagged up by both anti-virus apps?
