Got a message from Google to say there may be some warnings when logging on as they suspect someone has added a 'phishing' link to the site .... all OK with me but be cautious about redirection, we are investigating!

"We recently discovered that some pages on your site look like a possible phishing attack, in which users are encouraged to give up sensitive information such as login credentials or banking information. We have removed the suspicious URLs from Google.com search results and have begun showing a warning page to users who visit these URLs in certain browsers that receive anti-phishing data from Google."
