Yes... let me be very quick to jump on this, as well...
- It is *not* possible for any WoW add-on to keylog your password or otherwise compromise your computer's security unless it contains an executable program that runs *outside* of WoW.
- Add-ons are not loaded until AFTER you have logged in to WoW and add-ons cannot communicate with the outside world. Therefore, it is *impossible* for any proper add-on to "hack" your WoW account. Period.
- I know that Cairenn, Dolby and crew are meticulous about screening their add-ons. The odds of you having downloaded anything from this web site that compromised your account are somewhere between zero and none.
Things I would look for...
- Do you use WoWMatrix? If so, it has been implicated in the past in similar things (though *never* proven).
- Do you run an anti-virus program and a firewall?
- Do you have a secure password? (as in a password that could not be guessed if someone knew your user name and/or knew you in real life?
- Do you use the same user name and password for web sites you join as you do for you WoW account and things like that? (something you should *never* do).
