How to uninstall Symantec Endpoint Protection 11 WITHOUT the uninstall password

So you inherited a PC? Sweet. But dang, it has Symantec’s crapware Endpoint Protection 11 on it. Tried uninstalling, but you need a password? Don’t know it? Sorry dude.

Actually, there’s good news. There is a way to remove SEP 11 without the password. The first (and easier) way is detailed here. Unfortunately, that way didn’t work for me (I think Symantec disabled it in an update), so I found another way to remove it.

Disclaimer: Don’t do this on a work-issued PC. Your company may have policies about such things, which, if violated, could get you in trouble.

Steps to remove Symantec Endpoint Protection 11 WITHOUT knowing the uninstall password:

  1. Click on Start -> Run (or Window Key + R if you don’t have the Run menu item)
  2. Type smc -stop. If it prompts for a password, open regedit (Window Key + R; type regedit; hit ENTER) and then navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\SMC. Look for the smcexit key, delete it, and then type smc -stop in the Run box again. Note: my key was called smcexit-test or something like that, but deleting it had the same effect.
  3. Now, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\SMC. Look for the smcinstdata key; delete it.
  4. You should now be able to use Add/Remove programs (or Programs & Features in Vista & 7) to remove SEP 11 without supplying the uninstall password.
  5. You’re now free from the shackles of Symantec. Enjoy a 10-15% performance boost. :)

For a free replacement antivirus/anti-spyware program, I’d recommend Microsoft Security Essentials. I’ve used it for a couple years with no problems, and it seems to go easy on my system resources.

Did this guide work for you? Let me know either way below.

    I was trying to install Win 8. Symantec Endpoint Protection was not compatible with it. So I tried to uninstall, it asked for a password and I did not know it. So I tried your method but as Vladimir said, the file reappeared instantly. So I did as Vladimir mentioned, revoking the settings. But when I uninstalled it again, it said it could not read the key and it cannot uninstall. Any Solutions for thins. I am really bugged this antivirus program Thank You

  • Vladimir

    I’ve found that when I delete SmcInstData key, it immediately returns back, so uninstall process requires password again. I’v tried Flair’s method several times, but unfortunately. Then I’ve changed security settings for registry branch, containing this key, namely, revoked permissions for all user including SYSTEM (break of inheritance needed) and it has stopped to appear! After that uninstal process runs successfully without password!

  • Padiamon

    Thanks a lot.Works so nice .

  • Anup Vishwakarma

    It really works. I don’t know how others are not able to do it.

  • Flair

    Wait! I’m trying again after seeing “frustrated”‘s post re: smcinstdata coming back. I failed to notice that it did show up again in the registry. I removed it again, then immediately tried the uninstall. It just finished and is prompting for the reboot. Thank you!

  • Flair

    Fun thread. Thanks to all you contributors, I’ve got smc SEP stopped and not starting as a service. But I cannot get it uninstalled. Still prompts for password. My installation (v.11.0.6005.562) does not have the smcexit key (or anything like it). It does have the SmcInstData key, but I’ve deleted it and still get the password prompt. I’ve got MS Sec Ess running, so I’m fine, but I’d like to get the uninstall completed. Any *more* ideas?

  • John M. Keller (ITBeast)


    Just to let you know I am a Windows System Administrator on a development Network with a Big Name Defense Contractor. So I do qualify as the one person who can legally remove Symantec Endpoint Protection from a PC or Server, but I did not remove the anti-virus for most of the reasons listed (Hate the program, inherited the PC and it came with it, and so forth). My reasons for this is the previous Windows Admin on this project did not leave any of the passwords for this project so I could update the skylink file (this is what replaced the grc dat file in previous versions of Symatec Anti-Virus)so my management console could mange the anti-virus clients on my projects pc. I would get the “Enter Password” Box. Your method allowed me to update the skylink file and update the clients without having to either remove or rip out the symantec Endpoint client, Thanks for making me look good.

  • Brad Smith

    You rock man it actually works.

  • davisbr

    You are the bomb. I tried a few other methods, including the Help Desk Geek one, trying to kill the msiec (I spent over two hours and multiple restarts trying that one LOL).

    I did disable all the Symantec services, and renamed the ccapp file in the program files\common shares\symantec folder prior to finding your page.

    NOTE: To disable the “one service that won’t let you stop it or disable it” (I think it was Symantec Management Client) …just go into services, and first disable it, then click the Recovery tab and change all the failures to Take No Action and in the Log On tab choose to This account, and enter a user with administrator rights (create one if you don’t) and enter in the password (create one if you don’t have one) and apply. And restart.

    …the smc -stop from the Run worked fine (no error …and I didn’t even see an smcexit key), and was able to immediately delete the SmcInstData key.

    And when I went to Add-Remove this time, and clicked the Symantec Remove key, there weren’t ANY questions. It took awhile removing, and then a pop-up said I needed to restart.


    Thanks very much!!!!!

    Perfect…it works for me.

    Worked amazingly! Perfect guide. Thank you so much!

    Andrew, I have tried to follow your commands to delete Symantec to no avail. Once I type the msc -stop I do not get any response. Please advise. Ricardo

    Problem solved. Password still set to default: “symantec”. Uninstall worked perfectly first time.

    Didn’t work for me. smcinstdata keeps coming back after deleting. Any ideas?

    Hi Andrew

    Just FYI, on Symantec Endpoint Protection 12 it doesn’t work. This reg key no longer exist… any thoughts?


  • Andrew Block

    Thanks, Mark. It really had its “hooks” in your system, didn’t it? Almost like a…virus? Coincidence? You be the judge. :)

  • Mark

    This worked for me after 3 attempts (the deleted files regenerated each time I restarted the pc).

    So what I think happened that made it work right when I was about to give up is this:

    After deleting the files in steps 2 and 3 I ran the -smc stop command from step 2 again and this time I was not prompted for a password.

    Then I went and reopened the add/remove programs in control panel and clicked to remove the program. To my dismay the password window popped back up again. I closed that password window but I left the add/remove programs window open.

    Then I noticed that the smc_exit_test file had regenerated. So then I deleted it again and went back to the add/remove programs window that I left open and clicked on the remove button next to the Symantec Endpoint. All of a sudden it worked!

    I don’t have an explanation for how this happened.

    I will never use a Symantec product again.

    Thank you sir for freeing me from the grip of death of that parasite!

  • Timon

    Hey Andrew!
    First i’d like to thank you for this posts, it helped me alot. Now to my problem:

    I’ve had a Trojan yesterday, the notebook is NOT in the company network actually. Now i deinstalled Symantec. Will the security people get a notification about the infection anways? I hope not, otherwise i think i’ll get in big trouble. :(
