Not all Android phones are equal. Not all of them come clean and new. Not all of them are free of malware when you unbox them… This probably won’t be surprising for many of our readers as we have seen similar reports and stories several times in the past, but Avast is giving all of us a good reminder.

The antivirus maker who is currently trying to make things work with the latest Windows 10 version has discovered several hundred different Android device models and versions that come with malware or adware preinstalled. In case of adware, known brands like ZTE are also included in the list of offenders. “The majority of these devices are not certified by Google,” Avast wrote in its latest blog post.
