The Cloud@mail links usually contains folders so you can see what files are inside but I think it just throws up a warning for every .rar file as it can't see inside them. You just have to tick the box and click confirm if you're okay with downloading it.
If you're using chrome, you should be able to translate the page by clicking right click somewhere on the page or clicking on the translate icon at the right hand side of the address bar.
But it looks like the product has been deleted now so maybe it was actually infected?
