The level of sheer stupidity you are displaying is reaching critical mass here.
Did you seriously try to compare the breach of sensitive data on a corporate network (such as the Breach of the Blizzard account database) to people getting malware and keyloggers because of bad browsing habits!??! Are you bloody kidding me?
How do you manage to post something that dumb while honestly believeing you are somehow making a logical arguement?!?!

There is a WORLD of difference between what happened to Blizzards servers to result in data compromise, and what happens to the general internet user to result in data compromise.
When a user is compromised, the VAST majority of the time they are effectively GIVING their info away, either by visiting bad sites, clicking phishing email links, or generally doing dumb things. No amount of security will prevent that. That is why most of the people who DO get compromsied without authenticators, end up almost immediately getting compromised AGAIN after they get their account back.
When someone like Blizzard is compromised, it is because someone out there made a concerted effort to attack their systems.
Trying to compare the two is about as dumb as comparing someone being injured because they were Intentionally Attacked, to someone being injured because they walked into an open manhole.

The point I was trying to make is, to lessen your chances of getting them(ad-block/noscript/av/not clicking on the lottery winner from Nigeria). Nothing is a 100% safeguard against getting viruses/malware. Even the all mighty authenticator isn't 100% safeguard to your WoW account.
