Yes, in extreme cases.  I don't know why Oliver thinks otherwise.

To clarify, I did not want to suggest that Virustotal or the AV
vendors are doing something nefarious.  It's just that there automated
processes whose effects can be surprising.  This makes sense for
various reasons.. Some malware authors use Virustotal to test their
creations.  Here's one case which is quite well-documented:

It has to be a false positive with a certain level of AV detection.
It doesn't work for files with no detection.
