I too deliberately avoid products from ads, especially ones that annoy me. But I'm under no illusion that ads never work on me, "there's no bad publicity" and all. It takes active effort to avoid defaulting to the options you have already been told about and sometimes you're going to slip up. And since about every company advertises it's not like you really have any other option.
The most likely way to get me to not buy your product is to advertise it to me.
