In my view there has been enough successful attacks which used ad networks to launch the attacks that I consider ad blocking primarily as my first line of defense.

For example, some years ago here in Norway a fairly popular site got their ad network exploited to serve an exploit which installed malware that hijacked the pages of the largest bank. When you think you sent money to your kids or paid a bill, you ended up sending the money somewhere else entirely.

So for me, it just isn't worth the risk, and I won't surf without an ad blocker.
