Uninstalling Sophos Antivirus version 9 for Mac - the web site documentation is incorrect

[It's undocumented, but after I wrote this I discovered the Antivirus 9 install puts an app called 'Remove Sophos Anti-Virus' in the Applications folder.]

---------

In a moment of madness, I installed Sophos Antivirus.

Forgive me, I have sinned. It's a mess.

Unfortunately, the online documentation for version 9 removal is incorrect: Using the Terminal to install or remove Sophos Anti-Virus for Mac OS X. 'Remove Sophos Anti-Virus.pkg' no longer exists and there's no longer a GUI uninstaller.

Instead you have to run remove_v9.sh. I tried to do that from my Admin account -- but that failed. You have to run it from the account it was installed from, even though this app is a root install and the original user account might not be an admin account. This worked from my non-admin account in OS X Mountain Lion where Admin is my Administrator account:

jfaughnan$ su Admin Password: bash-3.2$ cd /Library/Sophos\ Anti-Virus bash-3.2$ sudo /Library/Sophos\ Anti-Virus/remove_v9.sh Password:

I got this ...

if there are errors reported by this script, run it again (it fixes itself)

 It didn't "fix itself", but I removed the residual paths manually. From an earlier failed effort I suggest also checking (Library is not user Library, it's root):

error: leftover path /Applications/Sophos Anti-Virus.app/ needs to be removed error: leftover path /Library/Frameworks/SAVI.framework/ needs to be removed error: leftover path /Library/Frameworks/SUMScanKit.framework/ needs to be removed error: leftover path /Library/Sophos Anti-Virus/ needs to be removed error: leftover path /Library/Caches/com.sophos.installer/ needs to be removed error: leftover path /Library/Caches/com.sophos.sau/ needs to be removed error: leftover path /Library/Caches/com.sophos.sav/ needs to be removed error: leftover path /Library/Caches/com.sophos.sxld/ needs to be removed error: leftover path /Library/LaunchAgents/com.sophos.uiserver.plist needs to be removed

What a mess.
