I installed a Norton Security Suite for Mac offered by Comcast.
My system performance degraded significantly afterwards.
I tried uninstalling the software but couldn't find any "uninstall" menues, so I physically deleted the apps.
Now I have had 2 system panics, black screen freezes and automatic restarts.
I combed my system again and found some com.symantec.kexts in my system library extensions.
I removed them.
Now I have a startup warning "Norton Virus cant be loaded because the extensions need to be updated."
How do I delete whatever is triggering this warning and get ALL Symantec files, extensions, apps, scripts...EVERYTHING off my Mac and out of my System?
Prior to installation of this software, I had NO PROBLEMS.
