With the upcoming element BASE (aka alkali) being immune to virus, ACID should be immune to virus as well; alkaline materials kill pathogens in real life (like the ammonia in Windex or the bleach in Clorox) and so do acidic materials (like the gastric acid in your stomach that is the first line of defence against pathogens in your food or beverage) so we should make ACID dissolve virus like BASE will.  This won't break saves because no one is infecting ACID with virus.
