Wily based Zero on the design of MegaMan X.
Therefore, Zero is a reploid.
IIRC that is how reploids are described in the manual for the first X game, X was a new type of robot that actually had free will rather than the simulated almost free will of the original series.
Reploids were Machines that had true free will like X, but were loosely based on his design. In fact IIRC Dr. Cain said he fully didn't understand lights notes so they are actually quite different from Light's design. How closely Wily followed Light's plans is up to debate.
As for the Mavericks that appeared before Zero's activation. It is possible that they truly hated humans freely as they have free will and except for the fact that they are machines are no different from humans. It is also possible Zero had been spreading the virus for a long time before he was active.
