Norton Mobile giving Twitter App a High Risk rating?

I have noticed that some of my Android Apps are rated as Medium Security Risks and reviewed the reasons why. Some reasons were acceptable so I ignored, some were not so I deleted the apps. Today, I went to download Twitter and found it was rated as a High Security risk. The reasons looked pretty substantial, so I deleted it. But Twitter is an app that is quite a bit more useful on a phone than on computer, so I am curious if others have had this dilemma and what they decided to do?
