I have had occasion myself to submit a 'false positive' to Kaspersky,they duly 'whitelisted' it.
Unfortunately it appeared that their whitelisting process is machine-specific, the file in question no longer triggered an alert on my system, but it still showed as a threat on everybody else's system, just not mine. As I already knew it was false-positive, the process was rather pointless.
Even on my own PC, after copying the harmless file to another location on the same HDD, it was once again wrongly flagged as a virus.
That did not surprise me. If AV vendors were to globally whitelist, just on the say-so of an individual user, obviously, they would soon come to grief.
