Hello Bryant,

Please use the Application Control signatures to block the functions you want disabled on your policy. Go to your App Control sensor and do a Name filter for QQ and WeChat and you should see a list of sub functions like QQ_File.Transfer, QQ_Picture.Transfer, etc. Set those signatures to Block.

Hello Bryant,

Can you do a packet capture when you are trying to send files out? I will check and see what is wrong? You can send me the packet capture in a PM. Thanks.
