Derived from the word spyware, "apyware" is an intentional typo used to describe anti-spyware. The reason
why it is intentional is that many people type the "a" instead of
the "s" when searching for "spyware" and when they do,
site owners who have included "apyware" in the meta tag will appear in the search results. Many anti-spyware product
reviews in blogs and forums are tagged with the term "apyware" so that these Web pages will also appear
in organic search results.
