This is happening a lot lately and Google is not aware of all of them. The one I clicked on did not have a warning that it could harm my computer. I got the fake Security Advisor screen and luckily I got out of everything without getting the virus it wanted to download.
the address of that particular site is hastenhouse.com
others that may be like it (they come up in Google searches for quilt patterns also) will be some name plus hotel.com, example whitedreamhotel.com
Please warn others to only open links to shops or manufacturers you are familiar with. Hopefully Google will fix this soon. I sent them an email about it.
