Upload Problem

Well , I’m new to uploading to garrysmod.org but when I upload , the file gets “auto-reported” for virus or some , link : http://www.garrysmod.org/downloads/?a=view&id=91191 . I would like to know what I’m doing wrong
P.S. It’s not a Virus , if it was i wouldn’t take screenshots of sweps
EDIT : The first file I uploaded was ok but the second one ( update ) was reported
EDIT2 : Is it because file exceedes 100 mb?

Make sure it doesn’t have .zip files within the .zip file.

I’m 100% sure I have the uploaded zip archieve on my PC and it doesn’t have other zips inside

Post a screenshot of the contents of the .zip file then.
