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 page shows the different variations of the Antivirus from an Icons8 icon pack. Feel free to resize and recolor the icon, and then download the icon in PNG format for free.
