Program download problems after installation of Norton Internet Security

Dear all,

 

Ever since I have had Norton Internet security, I have realised that it has prevented me from watching video-streaming online.(The video stops loading at around the 1/4 mark.)

Moreover, most of my internet downloads stop even before the halfmark.Does anyone know why this is occuring,

I am using a 3-user internet security and all 3 computers are facing the same problem.If anyone has knowledge of how to resolve this issue, please inform me.

 

Regards and thanks in advance
