If you visited hayley-atwell.co.uk, hayley-atwell.com, smoking-pics.com, or more recently south-lake.com (posted by rockchalk aka frundy11 aka frankly aka johnson11 aka johnson111), and downloaded the "plug-in", you computer is most likely contaminated by a virus.
You can check to see if you are affected by going to your Control Panel, then your Add/Remove Programs (or Programs and Features in Vista), and look for "Codec", with the publisher listed as Gentai. Uninstall the codec, and run both your anti-virus program (and Microsoft's Malware detector for good measure, but download this only from microsoft.com).
We are deleting the users and the domains as quickly as they pop up on SideReel, but like roaches, they always find a way to come back and multiply.
Thank you for your attention.
