"A quantum virus is a sort of disease of spacetime. You see, it slowly breaks down the force that holds subatomic particles together. It slowly disintegrates whatever it affects. Living creatures affected with a quantum virus find their very molecules breaking down. It can take days, weeks of agony."

The Quantum Virus is a "disease of space-time". It's an advanced simulated-life program that is a combination of Andalite physics with Arn biology and genetic knowledge. It's composed of tiny airborne units which apparently are structured like viruses: they are programmed to slowly break down the force that holds sub-atomic particles together. Living creatures that have had the virus specifically programmed to attack them, will face weeks or months of agony while the virus slowly breaks them apart at the molecular level.

It was used in The Hork-Bajir Chronicles, where War-Prince Alloran-Semitur-Corrass had programmed it to kill all Hork-Bajir, from the Hork-Bajir Controllers, to all the free Hork-Bajir that were still alive, to prevent them from becoming enslaved. Aldrea-Iskillion-Falan unsuccessfully attempted to interfere with its release.
