  • Remove any app installed with these name on your iOS device : 情涩播放器”, “快播私密版” or “快播
  • Go to Settings -> General -> Profiles, and remove all untrusted, unknown and doubtful profiles
  • iTunes won’t help in this issue. So you need to use any third-party iOS management tool, like iFunBox on Windows or Mac OS X, and connect your iOS device
  • You can check all installed iOS apps in Management tool; if you find apps with such names, like Phone, Weather, Game Center, Passbook, Notes, or Cydia, delete them. Don’t get confused, this process will not remove or affect System apps, but only infected apps or the apps YiSpecter has installed or replaced.

TechCrunch contacted Apple about this issue and Apple gave these statement:

This issue only impacts users on older versions of iOS who have also downloaded malware from untrusted sources. We addressed this specific issue in iOS 8.4 and we have also blocked the identified apps that distribute this malware. We encourage customers to stay current with the latest version of iOS for the latest security updates. We also encourage them to only download from trusted sources like the App Store and pay attention to any warnings as they download apps.

It means you must update your iOS device to the latest version. Using older version could be the reason to get infected. However, Apple didn’t say anything about older models that cannot be updated to iOS 9. So you need to follow the removal process that we mentioned to get rid of the infection.
