I'm receiving the above from two websites so far, starting this morning. Sites are www.elance.com (a bit deeper into the site) and now also from news.yahoo.com (specifically l.yimg.com 209.73.189.129,80) attacking 127.0.0.1, 1772)
Both these sites were fine about 6+ hours ago and I've never rec'd this error before.
I'm using NIS 2008, update to date with all updates.
