I have Norton AntiViruse version 19.9.09 and it failed to detect and protect against zybfgzg.dll. I was able to install and run Norton Power Eraser which said it found zybfgzg.dll as a Startup Item and Status "Bad" and the fix was to remove. It looks like it removed it and the IE9 which was redirecting Google searches now seems to be working correctly.
The problem is I want to verify and learn more about how I was infected but there is no information on Norton's site, in this forum or through searching with Google and Bing.
Does anyone know more about this virus and what another name would be?
