greenlife.no is loading ie instances that redirect to anti-virus software (koobface)

A friend was using my computer and attempted to download flash from an unknown website and inadvertantly infected my computer with a virus. From time to time a new tab opens in IE with a url beginning with greenlife.no that then redirects to a site selling anti-virus software. Has anybody seen this particular virus before? The link was on facebook by the way.
