Beware ... very clever Virus circulating!

just received an email from my ISP, very official looking, all the right
references with the administrator (have his name correct) telling me
their virus software is detecting outgoing viruses from my computer and
to use this provided password to enter their in-house anti-virus
software from within the 'attachment.' of course I never open an
attachment unless completely sure so I called my ISP as it sounded a
little fishy and yea, they told me if you click on the attachment, use
the web link, apply the password, YOUR SCREWED!

this is what it looks like: plus the deadly attachment!
