Benign samples for testing AV vendors

["Bridges, Robert A." <0000008d8011d045-dmarc-request () LISTSERV EDUCAUSE EDU>]

Hi, we’re planning on testing some AV vendors products. Is there a good way to collect or download known benign files 
for many different OSes, specifically Windows 7, 10, and RHET distros?

Thanks
Bobby
