How to remove Symantec Endpoint Protection ver. 11.0.4202.75

Created: 09 Mar 2013 • Updated: 10 Mar 2013 | 4 comments

This computer was given to me because it was infected with malware and the previous owner desided to get a new computer rather then fix this one.

I was able to fix the problems and keep the files intact, however after a few months it got infected with malware again that kept using up all the free space

on the hard drive. Undetected by Symantec Endpoint Protection. I purchased Norton 360 which I was unable to intall for lack of disc space. 

Trend Micro House Call, AVG and a couple others failed to detect the problem. I finally used Avast Free Edition which detected the problem and is

preventing  a reinfection, However Symantec Endpoint Protection is still installed. I tried to remove it but it wants me to use the Administrator Account and

Password that was used when it was installed. Unfortunately that Administrator account information is no longer available. I decided to just leave the

Endpoint Protection installed since it didn't appear to have any adverse effects but now I am getting a Message that says the virus definition files are old. 

WHen I try to update the definition files I get an error that says "Live Update Start failed  Error code -536805375".  Now due to the fact that AVAST is doing a  

great job I would like to remove  Symantec Endpoint Protection.  Can anyone tell me how I can remove it without the original Administrative Account

You can call up Symantec Technical support to address the Liveupdate issue. If you still want to uniunstall yu can use cleanwipe tool, this can be got by asking technical support team.

Alternative is to use manual uninstall method.

You can only uninstall the antivirus if you have tha access of application uninstalltion because limited admin access is require to install/uninstall the application. Try the Cleanwipe tool, I am not sure because it remove registry entry and registry will be accessible in admin account but may be it work so try it.

How to get the CleanWipe tool (Endpoint Removal)

New Cleanwipe version is introduced in SEP 12.1 RU2

Better option is that if it is infected and not connected in network then format the system and install the sep or update it.

For the virus cleaning try it
