I removed Norton after having problems with it interfacing with MacOS on many levels. I proceeded with the standard Norton uninstall and found that it seemed to work. However, when adding Avast I found that Avast will not install due to existing Norton/Symantec files existing.
I have tried file cleaners and the standard norton uninstall cleaners.
It seems that 4 items still remain and I am unable to remove them.
when running
kextstat | grep -v com.apple
i find:
com.symantec.SymXIPS (9.0.1)
com.symantec.internetSecurity.kext
com.symantec.nfm.kext (9.0.0)
com.symantec.ips.kext (9.0.1)
When trying to unload am met with this (below) or a kernel panic.
Password:*****************
(kernel) Can't remove kext com.symantec.internetSecurity.kext; services failed to terminate - 0xdc008018.
Failed to unload com.symantec.internetSecurity.kext - (libkern/kext) kext is in use or retained (cannot unload).
Through some research I have found that some resources have stated that I should enter safe mode and run csrutil disable
(due to having File Vault enabled)
Yet again after restart I get the same error of unable to terminate and Avast still fails to install.
