Norton claims they're capable of removing it: http://community.norton.com/t5/Norton-Internet-Security-Norton/Startnow-com-virus/td-p/482820
Haven't had trouble with it myself, but you're probably not going to remove it simply by uninstalling or running AVG without first booting into safe mode.
How do I get rid of this page that keeps popping up when I open Google Chrome. I tried to go to the control panel and uninstall it..but it is still there. I uninstalled Google Chrome and then ran AVG and then reinstalled Google Chrome and its there again
