NortonAutoProtect and SymAVScanDaemon are memory hogs

Both the NortonAutoProtect and SymAVScanDaemon processes are taking up a significant amount of system resources (about 410+ MB of RAM respectively) -- far more than any other application I have running.  Is this normal?  Is there anything that can be done to lower this amount of memory usage on the system to improve performance?



Re: NortonAutoProtect and SymAVScanDaemon are memory hogs

The amount of memory used by those processes is directly related to the virus definitions. The more virus definitions, the more memory that will be used. However, that memory is not all kept in RAM at once. Most of it is written to virtual memory (hard disk) so it's not really taking up that much memory.

It sounds like you are running Norton Internet Security 4/Norton Antivirus 11. The latest version of the product, Norton Internet Security 5, made some big gains in this area as well. In fact SymAVScanDaemon no longer exists. If you are running Mac OS X 10.7 or later I'd recommend upgrading to the latest version.
