I really really don’t like web ads. Fortunately I haven’t seen one in almost a year (almost). I use a program called Admuncher. It blocks all web ads including inline and popups.
A regular banner ad gets replaced by a simple [munched] text link.
It costs $25 but has saved me from viewing 162,555 ads and 1.269 Gigabytes of bandwidth.
It is fast, lightweight and stays out of the way. Recommended.
