It seems all too often that when uninstalling Symantec Antivirus you are stuck with a partially uninstalled product. In some cases bits linger in add/remove programs, in other cases MS Word stops working. Whenever it happens its a big pain to fix.
A colleague of mine has received this tool direct from the Symantec technicians. Here are some details of it from its PDF documentation.
Symantec Enterprise customers have expressed a need for a way to uninstall Norton AntiVirus Corporate Edition (NAVCE) or Symantec AntiVirus Corporate Edition (SAVCE) when normal uninstall procedures do not work.
Symantec Enterprise Support has created a standalone application / utility to fill this need. This utility will uninstall NAVCE or SAVCE Parent Servers and Clients through registry and file system deletions.
