Yes, what the lone tenno above me said.

The problem is that people seem to think of shields and armor as being the same thing. Shields can be bypassed entirely by Toxin damage, dealing damage directly to health. Because Toxin bypasses shields, it also applies its +50% health bonus immediately.

Armor does not work this way. The +75% bonus against Ferrite only applies while the target still has armor remaining. If stripped away with procs, then the bonus of Corrosive no longer applies. However, the next shot fired will hit health instead, so if the next shot is Viral, it then gets a bonus.

What's interesting is seeing how this interracts with weapons that can produce both. Normally, they can't. But as an example, modding a Rakta Cernos to deal Corrosive damage causes the arrows to eat armor fairly quickly. If used on a higher-level enemy, you can actually finish off their armor with an arrow, then the AoE Blight proc, which is Viral damage, will get its bonus against their health. The same can be done with a Corrosive-modded Mire or any other weapon using the Blight effect, or you can apply Saryn's spores to a target, then strip away its armor. When you do, you'll notice the damage ticks after the removal of armor are much more damage than before you stripped the armor.

For maximum fun, get an Embolist and mod THAT for Corrosive, with the Toxic Blight syndicate mod. Use this with a saryn to quickly pop your spores, spreading Viral everywhere, while also rapidly building Corrosive stacks from the weapon itself. Probably the best way to see these two interact in a single gun.
