SiteAdvisor Site Safety Ratings

Provide the domain of a site you wish to test.
SiteAdvisor will tell you how that site rates for
presence of adware, viruses, spam, etc.  This is very
useful before downloading from an unfamiliar site.

The following forms of usage work the same:
   safe yubnub.org
   safe www.yubnub.org
   safe http://www.yubnub.org

If you give it part of a domain name, or a full 
URL to a particular page, e.g.,
   safe yubnub
   safe yubnub.org/command
then you will still get the results (albeit 
more slowly) as it will show you a list of
likely matches, from which you can then
select the intended site.
