A false positive of norton mobile security

I have installed Weibo from google play store, and the app advisor tells me that this app has no risk.

https://play.google.com/store/apps/details?id=com.sina.weibo

But after mobile security scanned the app, it tells me that Weibo is a malware.

The app do asked for a lot of permission, but I`ve been using it for years, and I haven`t seen any malicious behavior.

 

So please fix this false positive.
