A couple weeks ago, I uninstalled Norton Security using the "Uninstall" feature of the software. I then reinstalled from a download from Norton's site.
A few days ago I noticed my fan suddenly going into overdrive. When I looked at the Activity Monitor, com.symantec.mes.systemextension was using over 200% of the CPU (100% of 2 cores). This seems happen every 20 minutes or so whether I'm using the computer or not. There doesn't seem to be any reason for it.
Norton Security 8.6.6, Build 2
Macbook Pro 2019, 64GB RAM, 1TB SSD, MacOS 10.15.7
Anyone have any ideas?
