i tried to download from mega but it sais i need flash (a very insecure platform) so i tried google drive
google drive said the files was a virus
i found a workaround you have to copy to your drive then download.
chrome may say it is infected click keep infected fiile.
it may be because i am using an older version of chrome on osx 10.7.5
the suggestion: you may want to try double zipping or even triple zipping (file.zip.zip file.zip.zip.zip)
password protect the downloads and post the password*
*= i just read on google that password protecting may not work as some programs may be able to see through encryption.
you could pack it in an installer package and encrypt that.
