Gnome themes

Is there is even software in themes? Opening the first theme I found (awfully long URL at the end of this post), I only discovered one small Shell script, Ant-Dracula/gtk-2.0/render-assets.sh, to convert SVG images into PNG images. Not software that the theme would run but software to create the theme, which is images and some CSS.

The awfully long URL: https://dl.opendesktop.org/api/files/downloadfile/id/1517121804/s/237ba987be77475c147391dace6f3261/t/1517699037/u//ant-dracula-no-mac-style-buttons.tar

Clamav scans for winpawn$ virii and does absolutely nothing to prevent or to remove the virii affecting GNU/lix, which by the way do not exist.
