What's the Story on the NIS 2009 Warnings for Virtualdr. website!!?

Not sure where to post this question, but I'm starting here.  I've been using the Virtualdr. website for pc questions for many years and am wondering now what happened there.  Since installing NIS 2009,  a box pops up that warns "this site (Virtualdr.com) has problems" every time I try to access their website.  Virtualdr. is an old, well known website, with thousands and thousands of posts.  It's hard to believe they don't know Norton is cautioning internet users about security problems there.  I haven't posted at Virtualdr. since I've been receiving these warnings or I'd post a message there myself and find out what's happening.  Is there anyone reading here who has any knowledge about this situation?
