Here is a script you can use to uninstall Symantec Endpoint Protection 10 or 11 client from your computer.
The script stops and removes Symantec services and uninstalls the program without rebooting your computer.
*************************
First, the script...

Second, a little explanation.
1. Go to the line that starts with "set "SEP11={... long string of numbers...}" This long string of numbers is the GUID that Microsoft uses to identify the client. To identify yours, open regedit.exe and navigate to "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall". On the left panel you will see the string of GUID's and on the right panel will be the corresponding application. You want to identify the one for your product (i.e. Symantec Endpoint Protection ...). In my case I am using Symantec Endpoint Protection 11, so my GUID is {3C1AE512-3C37-44FA-BA42-ABB721EC5B1D}. If you are using SEPM 10 you will have a different GUID. If so, then copy that GUID from your regedit session (right click the GUID in the left panel and select "Copy Key Name") then paste this into the script.
*******************************
Finally, you can copy the above text and save it in notepad with the filename "symantec-uninstall.bat" then double-click it to run it. If there is an error the script will let you know. If not, then you will be on your way to uninstalling Symantec Endpoint Protection from your computer.
Good luck!
