What are your "Symantec Endpoint" configuration recommendations for a developer PC? We do java development with Eclipse, IntelliJ, Ant and Tomcat. With "Symantec Endpoint" the build and server startup are quite slow.
Replacing or removing Symantec is not an option. See also https://stackoverflow.com/questions/111226/least-intrusive-antivirus-software-for-development-pc, http://www.codinghorror.com/blog/archives/000803.html and http://www.theserverside.com/news/thread.tss?thread_id=44775
With any on-demand anti-virus program, make sure your code tree (source and build) are excluded from on-demand scans. I have seen this change a build from taking minutes to taking seconds.
you can also exclude from scanning java.exe. Make sure you add eclipse.exe too, or make eclipse start as a java.exe process, there is info on how to do that in some question here too.
Not an antivirus thing, but I would also disable windows indexing service.
