Hi,

1. I can UPDATE  most of the client machines by "Push Install" remotely
2. They are from different versions: Version 9.0, vesion 10.0.1, 10.0.2
3. I update to Symantec Corp version 10.1.0.394
4. I can not update one of the client machine remotely; i physically come to the machine and "over-installed" by mappinto the parent server; after Restarting , it did not pick it up; it is still in the older version; i tried to remove the old version from Add/REm program, but it did not let me do it; Ok. i used the NONAV; i saw that the NONAV deleting a lot of files; i restarted again; tried to delete the older version of SAV, but still do not let me do it; i went to Registry and deleted anything related to Symantec Antivirus; restarted again, but the older version of SAV still there; it can not be deleted. I logon in the SAFE mode, and tried to delete, but failed.
5. Somebody has a solution for this ?
6. Thanks.

Greetings, tjie !

If the remote machine is using Symantec Antivirus 9.x or earlier version, NoNav will automatically remove it

Best wishes!

callrs,

The uninstall tool used in your link is SymNRT.  It does not work on Symantec Antivirus programs.  In fact, it may hurt the system if used for other than Norton Antivirus and Ghost programs.

War1,

1. I just want to try the solution from Callrs (I believe the best one); are you sure that it will damage the system (It means it will damage the Operating system of my client's machine ?)
2. I tried NONAV, but did not work (you said that Nonav can function for Symantec Antivirus 9.x or earlier ?; my client has symantec corporate Edition version 10.0.1.1000; so do you have a solution for this ? )
3. Respond back please.
4. Thank you.

Backup your system and try it.  I had a client who use the tool and had to reinstall system. There was a lot things wrong with my client's computer. So it could be some other problem that caused the reinstall.

>> 2. I tried NONAV, but did not work (you said that Nonav can function for Symantec Antivirus 9.x or earlier ?; my client has symantec corporate Edition version 10.0.1.1000; so do you have a solution for this ? )

NoNav does not remove some files in SAV 10.x.  The only sure way is to follow r-k's link and perform a manual uninstall.

Regarding NoNav.exe
I have just converted over 600 XP Pro workstations from various Symantec versions (mostly 10.x) using NoNav.
I only had to manually remove files from about 6.
The 'Magic Bullet' (other that NoNav) was CCleaner - using the Registry function.

war1, please quote some references that  state the tool won't work, can damage, etc.

Saying "It does not work on Symantec Antivirus" contradicts the aim of the tool: to remove Symantec (Norton) products including Antivirus....

I'm no fan of Norton though lol. I prefer the better AVG antivirus or NOD antivirus (http://www.grisoft.com , http://www.eset.com/ )

OK I loved the awesome Norton utilities though, to Norton's credit. Just not the antivirus etc.

callrs,

This is the statement from SymNRT:

http://www.majorgeeks.com/Norton_Removal_Tool_SymNRT_d4749.html
The Norton uninstall tool uninstalls ALL Norton 2004/2005/2006 products from your computer. It also uninstalls Norton Ghost 10.0/9.0/2003.

SymNRT does not uninstall Symantec Antivirus Corporate Editions software and NAV 2003 and before.  This is implied in the statement above and from personal experience.  It is a very good cleanup tool for NAV 2004-2006 and Norton Ghost 2003 to 10.

I posted above from my experience with a client using SymNRT to remove SAV and broke his computer.  Client had to reformat.  This is what I am warning about.

Jjie,
Sorry, I was not very clear with my statement.
1. We had to remove various versions of Symantec/Norton AV from over 600 XP workstations and notebooks (WAN with 130+ remote locations).
2. The Server Administrator forgot the Symantec CE password and we could not use the remote uninstall feature.
3. We used DameWare to do remote log ins and then attempt to do a 'manual' uninstall from the 'Add/Remove Programs' screen.
4. We had to use 'NoNav' on about 100 boxes, because the Add/Remove function would not work.
5. Of those 100, about 6 would not respond to NoNav.
6. Of those 6, I used CCleaner to remove all traces of Symantec.

Over the years, I have used NoNav and CCleaner on hundreds of XP Pro boxes and have not yet had any OS related problems as a result.

Good Luck,
Vic

Tjie (sorry about the misspelling above),
Occasionally I have had to run NoNav twice (or three times) to remove multiple installations of different versions of Symantec/Norton products.
Sometimes our Adminstrators get lazy and just install the new version of a product without removing the old version first.
The Norton products seem to function OK even with multiple versions, but the un-install process can get pretty messy.
