I tried to uninstall Minecraft then install it again which worked, but all my worlds were gone which was sort of fine, but they were still shadows. all I can see is the sky and if I look up, an outline of the tree. Basically what I'm saying is that imagine every thing, (except mobs and the sky) was pitch black. I think it may be the viruses in my computer, because I have about 9, but I'm not sure. please fix this.

thank you
