quote from linked article:

I should probably first speak about how adware works.
Most adware targets Internet Explorer (IE) users because
obviously they're the biggest share of the market. In
addition, they tend to be the less-savvy chunk of the
market. If you're using IE, then either you don't care
or you don't know about all the vulnerabilities that IE
has.
