No. Closing VirtualBox means that the memory usage should be released. If the memory is still tied up after the program has closed with no processes running, then the kernel is at fault as it is the one controlling memory.

Swap file is not being used. CPU usage climbs to %100 even as applications are shut down. After reboot, system will operate normally for a number of hours, until a virtual machine (Virtual Box) is run. At this point memory and CPU usage will climb until %100. Exiting programs and closing the VM does not resolve the issue.
