Blender-made model of a virus, with texture/material created using nodes. Model has an applied subsurf modifier, which is why the polygon count is somewhat higher than usual. Color is customizable if you're handy with Blender's shading nodes. I've also created a soft-bobbing animation which moves and animates the model up and down slowly over 60 frames. The renders should give an approximate feel for the animation. If you have any questions feel free to ask. Enjoy!
