There is very little difference in the systems in regards to them being compromised.
If you have a latent infection on your system, the merge may have grabbed enough information to ship off in a chunk. This is especially likely if you've had your account name saved and only needed to type in your password.
In any case, your system may not be as secure as you think it is, or your email could be compromised.
I'd highly recommend doing a deep scan for your own sake. That's not the sort of thing anyone wants on their system for far more reasons than just WoW.
This sticky may prove useful.

You may wish to take a break, but if you come back months later and want this done, we may not be able to do as much for you then as we can when this is fresh.
