Its just the lil pic saying security risk. I have the normal security settings that come with the vista package. i havent installed anything else. It is just the window that pops up with three options one says "get me out of here" the other says "add security acceptation"
That is built-into browsers and is there for a reason.
It means the site has a bogus or expired security certificate.
It is a rather sever warning.
It is not like the waterman saying 'Gusts of wind today is some places.'
More like the man saying 'Tornado warning 100 yards near your house.'
Of curse, the site might be harmless.
And the tornado could miss your house.
