An old friend contacted me today and asked me to help him to remove a virus infection on his desktop. I checked his computer and there is an enterprise version of antivirus called Symantec Endpoint Protection (SEP) installed but there were no Symantec Endpoint Protection Manager which acts as a server to manage the SEP clients on the network. It is possible that the Symantec Endpoint Protection is installed as an unmanaged client but the virus definition hasn’t been updated for a very long time and I couldn’t manually update the signature from the LiveUpdate program. I may as well uninstall the Symantec Endpoint Protection since it couldn’t update the virus definition to detect the latest virus and replace it with a free antivirus such as Avira, Avast, AVG or Microsoft Security Essentials.
I went to Control Panel and ran the Programs and Features shortcut icon. Found Symantec Endpoint Protection and I clicked on the Remove button. The progress bar ran for a while and a dialog box pop out saying “Please enter the uninstall password“.
I asked my friend and he don’t know the password. The Norton Removal Tool only works on home products but not for enterprise products. It is not possible for me to install any other type of antivirus if i do not remove the Symantec Endpoint Protection client first. Even if I could, it is still not advisable to be running two different antivirus at the same time which can cause conflict and slow down of the system.
After research, I found out how to remove the password so that I can uninstall Symantec Endpoint Protection. The first step that you should do is try a few possible password. Some of the most common password being used for Symantec Endpoint Protection are:
