Has anyone had an issue on a Mac that they run Virtualbox-based virtual machines on while Norton Internet Security 5 for Mac is installed? Application Blocking blocks both Virtualbox.app from any network access and subsequently blocks VirtualboxVM.app whenever any virtual machine is launched. Unless I catch the notification popup and manually use the drop-down box to select "Always allow this application," my virtual machine, regardless of the guest operating system, will not have any network access, including Internet. I have added both applications to the Application Blocking list and set both of them to "allow." This has not lead to any change in behavior. I inserted a Connection Blocking rule to always allow outgoing connections from Virtualbox.app which seems to have alleviated the issue with VirtualboxVM.app, strangely enough, but the primary application, Virtualbox.app, is still being caught and blocked by Norton Internet Security, so if Virtualbox.app (the Virtualbox console) tries to check for updates, as an example, it cannot get to the Internet to perform this task. This issue also seems to happen anytime the Office365Service.app launches whenever any Office for Mac 2011 application is launched, despite Office365Service.app being "allowed" under Application Blocking. I have not had the opportunity to see if the same or similar issue is present in other hypervisors such as VMware Fusion. Is this a flaw in Norton Internet Security or is it due to the design of Virtualbox? Anyone have any idea? Thank you for any assistance.
