problem in uninstalling norton anti virus

Have you tried to uninstall the old version of Norton with its own uninstaller,
not Add and Remove Programs?
Look at Nortons manual uninstall here:

If Michael's solution does not work try installing the old program again and then try again. This sometimes works if files are missing or corrupt.

Just a thought!

In addition to the other good suggestions, here are the manual uninstall instructions for most of the recent versions of Norton. The instructions include an uninstaller utility(RNAV2003.exe) that can be used when the standard uninstall doesn't get it done.:

i am trying to install a free antivirus and freewall software trial cd:

I received this message norton antivirus\nav95.isu is not valid or the data has been corrput uninstallation will not continue.

((I copied an e-mail thatI got from Donna. It worked for me, but I will take no credit if it works for you))


1. Uninstall NIS 2002, remove NAV too. If it asked to restart, do it.

2. Go to Control Panel, Add/Remove Programs, make sure no more entry of Norton Internet Security in the list. (Also, verify that there's no Norton Antivirus in the list). If there's an entry click Remove.

3. Look for LiveReg and Live Update in the list (in Add/REmove Programs) then remove these two.

4. Open My Computer, open C:\, open Programs folder, look for the following folders: Norton Internet Security, Norton Antivirus (if any), Symantec then delete these folders.

5. Empty your recycle bin

6. Go to Start, Search. Click all files and folders, click More advanced options, make sure Search system folders, search hidden files and folders and search subfolders are selected. Then scroll up, type Symantec in All or part of the filename, click Search. Once it's done searching, delete everything that you'll see at the right except if the files is located in your FAvorite links (just read the item and you'll see what I mean)

7. After deleting them (don't close Search window yet) empty recycle bin again. Type LiveUpdate in All or part of the filename and click Search button again. Delete all the items that showed up except if the file is located in your favorite links again. Empty recycle bin again.

8.. Type LiveSubscribe in All or part of the filename, click Search button again - anything it find - delete them. empty recycle bin again.

9. Open Regcleaner (I hope you installed this utility that I suggested to you). Under Software tab>author colum - look for Symantec entries. Put a check on the box for all symantec entries. Remove selected. Exit.

10. From Start, run type REGEDIT click OK. Click Edit, click Find and type Symantec, click Find now. Once it found symantec the entry is highlighted, right click on it and click delete. Click yes to delete it. Press F3 to find again, right-click again to delete the highligthed item. keep on doing this (F3 and rightclick and delete) until you receive a dialog box "Finish searching" NOTE: Be careful in deleting.. make sure that when it highligthed an entry .. read carefully the highlighted entry and make sure the word Symantec is there.

11. Restart your computer and install NIS again ) Note: before installing NIS, make sure no other programs is running so that it will not interfere with the installation.

Good Luck!!!
