Thanks to both of you for your answers!
Is my system, my primary harddrive with my OS (Windows) on it safe if I download the video on my secondary harddrive? Also, do I additionally have to put the video-player on my secondary harddrive too to prevent any risk of "contaminating" the harddrive with my OS?
Thanks in advance for your efforts!
PS::
@seyad: Is that title "symantec employee" a real thing - do you really work for symantec - or is it just a "fun" , ironic forum title?
Edit:
The download would be from a one-click-hoster.
