I know this cookie has a low risk and when I click on the fix button, NIS 2010 says it has been removed, but in the next full scan it shows up again. In IE8/tools/internet options/privacy/sites, under managed websites, I already have the domain atdmt.com listed as always block. Shouldn't that setting and having NIS 2010 tracking Cookies Scan set to "Ask me" prevent the cookie from returning to my PC or is there a parent file somewhere on my PC that keeps creating that cookie?
