I installed the latest version of Virtualbox on the official web site.
It is virtualbox 4.3.14-95030. When I installed and try to run the program, it displayed the following errors.
Error In supR3HardenedWinReSpawn
If you met same errors as me, go to download the Virtualbox 4.3.15
Here is the details of the problem.
Virtualbox 4.3.14 conflicts with anti-virus packages.
