All good advice Gary

, but what concerned me enough to post this is that when I read up on it this one looked like it would (Or already has) by pass a lot of those precautions as it was installed when you visited a website, no pop up, no form to complete, no email attachment.
Comming in as a component of a requested web page it would by pass the firewall, unless you were not using a fully up to date Internet Explorer with the security settings set to well past paranoid.
Basically I am usually cocky / careful enough to think i'll be unlikley to be directly affected by this sort of thing and this one made me think hard. Especially once I saw that it had been around for a while before the major AV houses got onto it.
