Neither Orcs nor Goblins were changed at all with the update. The ‘Charge’ ability of Orcs doesn’t work like you describe; neither can it hit multiple people, nor does it inflict any damage or break shields.
With Avast this may not be enough, I’m afraid. Other people have reported that they needed to uninstall it in order for it to finally stop messing with the game.
Did some testing and it worked fine for me. You posted in the other thread that you’re using mods; note that those may be incompatible with the current version of the game.
