The icon is a picture of the logo Antivirus Scanner. The icon is what appears to be a large circle with a small arrow shape at the bottom right on the outside. The icon has a picture of something that I can only describe as a microscopic germ in the center.
This Antivirus icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 5,500 icons, all in the same style and quality.
