On www.ursoftware.com when trying to dowload the ursetup.exe NAV 2011 (updated) indicate that the file is infected with a Trojan. The ursoftware.com tech support says NAV is detecting the packaged "Bing Tool Bar" as the trogon. This is creating a problem on their web site downloading any of their programs that has the "Bing Tool Bar" included with their file.
