Hey @agusrahman, here are my few suggestions on your post:

• The title should be more like Benefits of virus or Is Virus beneficial?
• The post is too short and doesn't explain anything in detail.
• You haven't properly cited the images. You listed three webpages as the source of the images but you have to provide the actual link to the image. Besides the images are under copyright. Please use only those images which are free for commercial usage.
• Your post lacks referencing. You have to list down all the sources from which you extracted the information.
