VBS.Bootconf.B is a Trojan horse that modifies Internet Explorer settings, redirects Web sites such as Google, Yahoo and MSN to a different search page, and may pop up browser windows to a pornographic Web site.
VBS.Bootconf.B may be installed by another script, which downloads a page containing VBS.Bootconf.B, and saves it as a file named win.hta in the Fonts directory (e.g. %Windir%\Fonts). Symantec antivirus products detect the downloader page as Downloader.Trojan.
