Oh that:D

That banner was added because there's a bogus LW update showing up in search results. It's a 75.7 KB .exe & shows up as "Urgent LW update - download & install now". If people download & install that thing they could end up infected. So, to make sure everyone knew that it was crap, the warning banner was added.
It's just to make sure everyone knows what's a real LW update & what's not.

The padlock symbol doesn't apply to music or video etc.

The only time you would need to worry would be if you had downloaded & installed one of those so-called updates;)

thanks birdy,now the only thing is now is to get my refund where i went to update and did not need to, i have emailed limenathan so maybe i can get to the bottom of this,now i have to wait on the mailman......
