this theme is not malware... its the perfect theme for windows 8.
even I had black screen problem when I installed certain other themes in my pc, but that doesn't mean tht theme is malware... black screen occurs when the particular pc doesn't have certain configuration.

im using this theme in my pc & my tablet n I don't have any black screen issue (this theme works perfect even with latest microsoft update, just use the updated files from - 'thomasking42').
