Actually, the reason is explained in volume 1. Each "real" guild member have a special aura around him that makes it possible for all the NPC in Nazarick to identify him as a supreme being even if he's desguised. Albedo being more intelligent than Yuri and CZ, understood immediatly that Pandora wasn't Tabula.

But you're on the right track, what happened in the treasury affected Albedo tremendously. Ainz wasn't able to hide his emotions from her there. When she understood how much Ainz is suffering, how highly he thinks of his comarades and how they abandoned him anyway. That's when and how her hatred of the guild came to be. In a sense, it contradicted with her settings. She can't help but hate what is causing who she loves to suffer.

That's why in the end of volume 3, in the scene where she extends her hand to Ainz, it's implied she saw through him and wanted to cheer him up.

She decided to go kill all the supreme beings for another reason however. In volume 7, when Hekkeran lied about Ainz's camarades being the ones who sent him, Albedo concluded from the way Ainz reacted that his camarades are his weakness, that's why she ruled them as a danger to be eleminated. It's her way of protecting him.
