You may host a single virus program on Progenitor. The memory cost of the hosted program does not count against your memory limit.

Whenever virus counters are purged, remove all but 1 virus counter from the hosted card.

If multiple viruses including Hivemind are hosted on Progenitors, then after a virus purge each virus retains 1 virus counter.[1]:Ruling


  1. Hivemind and another virus both on Progenitor
    If I have a Hivemind and a Medium on Progenitors, and a purge happens, how many real+considered counters remain on the Medium?
    They each go down to one, but then the Hivemind gives its one back to Medium for 2.
