Many of the download sites are cluttered with "extras" which you can usually avoid by selecting a custom install and rejecting all the add-on junk so I always try to obtain direct from the software originator where possible.
General rule of thumb is...... go to the manufacture's own website for downloading its products.
Example : I recently install the win 8.1 prop preview into my VMware Player.
I needed to install Malwarebytes ( I don't trust Windows Defender too much ).
I went to Malwarebytes website for download although it is also available in CNET which is well known and reputable by its own rights.
