How to un-install SEP

Created: 01 Aug 2010 | 8 comments

Trying to clean up my Mother's computer. Guess she had some version of SEP installed, probably as a free trial included when she bought her Vista PC. Somewhere along the way, she tried to un-install it, and it no longer shows up in Control Panel>Programs>Programs and Features. But when I try to install another virus scanning program, I get a warning that Symantec SEP is installed and will cause conflicts.

So how do I go about figuring out which version of SEP is installed, and how do I go about finishing the un-install.

I've seen lots of posts about 'cleanwipe' but I can't complete a registration with http://mysymantec.symantec.com because I don't have any info on the previous installation.

Any suggestions?
Sean

I guess SEP is not shipped with a PC it may be Norton antivirus. You can try downloading the below mentioned tool.  If you have the above mentioned folder posted by Prachand then you do have SEP, then dont use the below tool.

Thanks for the quick replies!

Only folders I can find are:

C:\Program Files\Symantec\
C:\Program Files\Symantec\Symantec Endpoint Protection
C:\Program Files\Common Files\Symantec Shared
C:\Program Files\Common Files\Symantec Shared\CCPD-LC
C:\Program Files\Common Files\Symantec Shared\COH
C:\Program Files\Common Files\Symantec Shared\DecABI

Can't seem to find a C:\Program Data or an "Application Data" folder. Could be they were un-installed, or that they may exist elsewhere.

Does this mean it was actually SEP?
(This system runs Vista Home Premium 32bit)

I think that is the left over of SEP uninstallation.So remove those folders manually...

Thanks, I will do that.

But my real problem is that when I'm trying to install another Antivirus program, it halts the install process and tells me that I have to un-install SEP. So it's likely there are registry entries that need to be removed in order to get a new antivirus program installed.

Delete following reg keys if present
HKLM\Software\symantec
HKCU\Software\symantec

No joy. Seems to still think it's installed. I also get a Vista Security Center warning that says SEP reports that it is turned off.

Searching through the registry for 'symantec' gives a couple of hits on:

HCLM\SOFTWARE\Microsoft\Security Center\Monitoring\SymantecAtivirus
HCLM\SOFTWARE\Microsoft\Security Center\Monitoring\SymantecFirewall

I deleted them also, but still no luck
