G’day Chim,
I prefer going to the original Skype website to get the correct download file size http://www.skype.com/en/download-skype/skype-for-computer/
Sometimes Major Geeks, CNET Download’s and FileHippo’s don’t always keep their website up to date, and it better to play safe by going to the true original Skype website to get the correct download file size otherwise somebody might shoot you in the rear with a double barrel shotgun
