Breakfast Topic: What are you doing to protect your account?

While it is certainly nothing new, it seems that you can't spit without hitting someone who has, or has had, a compromised account. These WoW account predators are getting more clever by the day, with using everything from keyloggers, sham contests, betas and security checks, to even grabbing an account and immediately attaching an authenticator to it.
Now, any moderately-savvy internet user would just scoff, and say that they take all necessary precautions -- what's there to worry about? Fair enough, but what about those who, well, don't?
Blizzard has said time and time again about safe-guarding your account information, yet people still jump onto those fake Cataclysm betas and fancy new mount prizes. Make something idiot-proof, and they'll build a better idiot, eh?
That being said, what are you doing to protect your prized polygons? Do you have a good anti-virus installed? A malware scanner? If you don't have an authenticator, how come? It's only about the price of a grande Starbucks drink, and will provide a longer-lasting effect of happiness and joy to your life.

Discuss amongst yourselves!
