Hi,everyone! Grin

I meet a very troublesome problem,and I ask for your help.

My host OS: Win7 ultimate sp1(x64)
Graphics card： ATI Radeon HD 6850

When I mine many coins based on scrypt,cgminer can run smoothly in my host OS.But I want to place cgminer and all coin's wallets into a virtual machine now,because my antivirus software always prompts that there are many viruses in cgminer and some coin's wallets. So I installed VMware workstation(10.0.1 build-1379776) today,and converted my physical computer into a virtual machine by using "Virtualize a Physical Machine".
But cgminer can't run in the virtual machine,and it prompts "No devices found". So I am ready to install the graphics driver,but I find that the graphics driver can't be installed successfully at all in the virtual machine.

So,I want to know:
1: Can cgminer run smoothly in a virtual machine?
2: If it can,how should I set the virtual machine？
3: If it can't,how can I run cgminer safely?
4: Is cgminer a virus?

My cgminer is downloaded from the link:

Why did you need to virtualize the machine?
