hi,

Discord is a VoIP, instant messaging and digital distribution platform or software designed for creating communities. Users communicate with voice calls, video calls, text messaging, media and files in private chats or as part of communities called "servers" for team management or one to one communication.

benefits of discord app is it can be downloaded on windows pc or android or smart  phone or tablet. the size of the software is less than 100 mb and it is easy to manage.

however it is recommend to use a anti virus protection in your device while you using internet connectivity or random apps.

hope it would help.
