Defenza is a rouge Anti-Spyware program.

As a SiteAdvisor Commentor states:
"The company that runs this site, CashEngines, has over six hundred web
sites. They use domain names that contain catchy phrases, in the hope
of catching the next unsuspecting consumer. The phrases "no fee" "free
unlimited" and "no spyware" appear often on their sites. It is worth
remembering that legitimate businesses don't need to resort to such
claims. If it sounds too good to be true...

CashEngines also is known as MarketEngines or MP3 Networks (perhaps
others as well), depending on the site you visit. Their modus operandi
is to get you to pay for something that is available elsewhere for
free, usually under the guise of "tech support."

The common themes appear to be video, music and software. Naturally, to
maximize exposure to their potential audience, there's a wide variety
domain names that capitalize on these themes. There's even the tired
old idea of recycling domain names to suit a particular audience, e.g.
thegamesmembersarea, themoviesmembersarea, thetvmembersarea, ad
nauseum. Do legitimate businesses you deal with resort to this? It
doesn't pass the smell test.

If you visit the cashengines.com web site, you'll see that they have an
affiliate program ("HUGE Payouts - Cash Engines pays affiliates up to
$22.50 for each sale you bring in"). Affiliate programs are a sure bet
that a good shopping experience for the consumer is an unlikely
proposition.

Addendum: it appears that CashEngines might now be getting into the
rogue anti-spyware business."
