Thanks Eric,
What Light is refering to is a gene deletion reaction to viruses, best seen on 1g bots, they delete any genes added by viruses.
Your virus will not work if it is deleted by the prey before it has the chance to work...
Also Light is refering to the idea that bots that are taken over by viruses, can in some cases, turn into copies of the original virus bot. Not that your virus would cause this.
