VirusTotal: Why Use It & How

This video introduces VirusTotal, a vitally-important free software scanning service I came across a few years ago and have been using regularly ever since.
My mistake in saying at about 9:10s that Softonic's guarantee was seen earlier in the video; that was Softpedia's at about 6:10s. But still, Softonic is also a trusted site that claims all its software is safe, and you can also see it listed as one of the safest sites in this video (see 6:38s).
