So here is my issue a friend is using AOL safety and security center. He previously had NIS06 and has asked me to remove it as AOL says its installed. So I uninstalled via the control panel. AOL still says NIS is there. OK, so I tried the norton removal tool.
AOL still says norton is there. Im getting confused, I checked the hd for anything that says symantec or norton and delete it. Did the same with the registry. AOL still says NIS is installed.

Im out of ideas, anyone got some help other than advise him to use a real antivirus or format the hd?
