BadImage error messages, possible Rootsystem infection

Ran a Norton scan recently and was infected by Packed.Generic.200 and Trojan.Metajuan.  Now getting BadImage error messages.  From looking at other similar posts, looks like I have a Rootsystem infection.  I use Windows XP, Mozilla Firefox after lots of problems with IE, and Malewarebytes.  Can you help?
