No spyware, no adware, no trojan horse, no bots, ... nothing excepted Virtual Desktop Toolbox itself. Virtual Desktop Toolbox installs a service called "R2d2 Kernel Authority" and a program called "Virtual Desktop Toolbox".
You will find all details about updated folders and files in the "C:\Program Files\R2d2 Software\VDTInstall.log file" (once VDT installed!).
To resume, VDT setup creates a folder called "C:\Program Files\R2d2 Software" and 3 registry keys called "HKEY_CURRENT_USER\Software\R2d2 Software", "HKEY_LOCAL_MACHINE\SOFTWARE\R2d2 Software" and "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\R2d2KernelAuthority".
