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