We don’t need antivirus software so McAfee is doing some authentication on our phones:
Pledge is a software token that makes your device an easy to use and cost-effective authentication token. With Pledge you can generate one-time password without Internet connection enabling you to authenticate to protected corporate remote access services, virtual desktop environments, bring your own device services, web applications, and cloud services. Pledge supports multiple tokens (Pledge profiles), customer branding, protection with PIN codes, easy-to-use copy and paste function for the OTP, self-enrollment of tokens (Pledge profile) and many more functions. To start using Pledge, contact your service provider or system administrator to get instructions how to enroll your device. Pledge is a part of McAfee One Time Password. http://www.mcafee.com/otp
