I suppose that my PC was a little bit confused, but I started the link "
www.opendcl.com" (from top of the "About" dialogue in Studio 8.0.5) with Internet Explorer on my Vitrual Machine and got this message from "MS Security Essential": see attachment.
The detailed report of "MS Sec. Ess." tells something about "Exploit ... / NeutrinoEKJ, webspript ...") - see other attachment.
Starting the same site on my PC with FF and IE got no alerts
