My forum home page has been hacked and the content that appears in the cashed google shows a canadian viagra site instead of mine.
The redirect is only for Google - see http://my.lifeinitaly.com
Searching on Google for Italy Community my forum description
is

dedicated to your privacy and security. No delays in delivery."

Clicking on Cache to see what is in Google spider memory I go to what
looks like a Canadian Drugstore company
