Malware Infection - OffersWizard

Hubbys computer keeps getting infected with these ad programs. I usually can clean it up no problem. This time the name is OffersWizard and it does not appear in the uninstall programs. What does appear to be newly installed is a Network System Driver, but when I try to uninstall it, my Norton popsup a notice that au_.exe is a threat and has been removed. But the item I was trying to uninstall does not go away.
I searched on the name OffersWizard and it references this Network System Driver but can find no answer to when it won't uninstall. I have also deleted all browser info and run full scans to no avail.
