Just upgraded from v4.1.22-80657 (no CPU hogging problem for this one) to the latest VB. Installed VB with both Bridging and Host-Only networking selected. However now just starting up the new VB (with no guest VM started) my 4.2 GHz quad core 2500K pegs in at 20% for VirtualBox.exe and 28% for VBOXSVC.exe according to Task Manager.
When using Sysinternal's Process Explorer and its Thread tab for the VboxSVC.exe process we find four rather CPU consuming ntdll.dllRtlValidateHeap+0x170 threads. For process VirtualBox.exe we have two ditto named threads plus a thread called VirtualBox.exeTrustedMain+0x2bc92c.
Nothing have changed in my software setup before updating VB. And if I go back to v4.1.22-80657 there's no CPU hogging anymore...
