this damn registry key wont go away. its an adware/spyware file. its disguised to be "Norton Anti-Virus Helper", hence the acronym "Nav". i have panda titanium antivirus, and every half hour or so i get "Unknown Threat Deleted" or something, and the location of the file is "SysRegistry/NavHelper" i have manually deleted this, file and key, numerous times. and i can sit there and watch it reappear before my eyes. can anybody help me get rid of this annoyance?
