 Posted: Sat Jun 27, 2009 1:25 pm Post subject: Running a virus in virtual machine |
 |
|
My primary question is this: Is it safe have a virus on a virtual machine? It WILL not spread to the other files on my host PC
And the gay explanation:
I have to reformat like every month because of viruses and rootkits and other shit. I never considered getting an anti-virus at the time (I'm a dumbass) but now I use Avira Antivir as recommended by a friend of mine. I want to be able to run programs that it picks up as a virus to check if it is a false positive or not.

There are some articles on people finding exploits in VM's that lets a program 'break out' of a VM (like http://www.linuxsecurity.com/content/view/149049/), so there is always a (small) chance you will get a virus that can possibly break out of your VM and attack your host system.
Some virusses also detect if they are running in a VM and chose not to run (this to prevent anti-virus companies running them for analyzation), so it can be safer (in my experiance most malware doesn't give a shit if it is on a VM or not, just aslong as it has internet access).
But yes, in general it is safer to run something in a VM than outside, just aslong as the VM has no networking or host filesystem access.

Running it sandboxed (using sandboxie) would be safer as it executes the file in it's own environment.
For more info; http://www.sandboxie.com/

An even better idea is to run SandBoxie in a Virtual Machine.
Double security...
I doubt anyvirus can double penetrate that baby

| Yes, if you have a virus on your virtual PC, you will get one on your host PC.

Wrong, and, "Virtual PC" is only one example of a workstation virtual machine.
Anyways, OP, unless the machine is networked, or there's an undiscovered vulnerability the piece of malware intends to exploit, you're fine.
Sandboxie is not as safe as using a VM in a majority of cases; using Sandboxie inside of a VM is one safer solution - or, running a process with limited permissions in a VM is one I would say is even safer.

Virtual PC, virtual machine, same difference. Pure wasn't referring to a specific program.
But, yeah, a virus run on a virtual machine probably won't infect your host machine, however there can always be exceptions.
