Can a zip file executable? For instance can you have a virus in the form of a zip. Obviously a virus could be inside a zip file but can the actual zip execute?
The reason I ask is I have a website that currently allows only jpg, jpeg, png and gif file extensions and I had an idea today to allow people to upload icon packs, but the icon packs would need to be in the form of a zip because there would be so many images.
I don't need my site infected by viruses.
