Does anyone have a script or powershell that will uninstall this program.
strComputer = "JWA-TEST"
Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colSoftware = objWMIService.ExecQuery ("SELECT * FROM Win32_Product WHERE Name = 'C:\Program Files\Symantec AntiVirus\vpc32.exe'")
For Each objSoftware in colSoftware
 objSoftware.Uninstall()
Next

sorry, I am not into shell scripting -- but I can tell you for CERTAIN, that it is worth uninstalling this Symantec component, which causes lots of problems.  I can offer an alternate idea, which is fairly easy to deploy on 500 computers, and will accomplish the same objective in the end.

1/  set a restore point on ONE computer and open REGEDIT.EXE
2.  export the registry to a file that you can search with Wordpad.
3/  find the offending Symantec entries and remove them.  
4/  export the changed registry to another file name.
5/ do a file compare at the command prompt --
       fc registry1.reg registry2.reg >diffs.txt

6/  extract out of diffs.txt the registry entries to remove.

The pattern is as follows --

file is fix-symantec.reg

"Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\symantec.1
@="symantec entry1"

that will add an entry

1/  set a restore point on ONE computer and open REGEDIT.EXE
2.  export the registry to a file that you can search with Wordpad.
3/  find the offending Symantec entries and remove them.  
4/  export the changed registry to another file name.
5/ do a file compare at the command prompt --
       fc registry1.reg registry2.reg >diffs.txt

6/  extract out of diffs.txt the registry entries to remove.

The pattern is as follows --

file is fix-symantec.reg, file contents as follows--

"Windows Registry Editor Version 5.00

- [HKEY_CLASSES_ROOT\symantec.2
@="symantec entry2"

that will remove an entry
end file contents"

Save this file as "fix-symantec.reg"

Now push it to one client to test.  Run it, when you debug and find it works, then --
Push it to all 500 clients, and tell them to run it before they get paid this month.

Result = problem gone.

damn, that post messed up.  Should read -- that will add an entry -- to "that will remove an entry:"

Please try to overlook the repetitious text.  I was merely trying to show how to add an entry, and remove one, using the - minus sign.  It is fairly simple once you realize how simple it is.  Check the links.
