Pretty much that, I’m going to be running Winxp in VirtualBox and I just wanted to know what the chances would be if worst came to worst?
lots of info online if you google your question. 
I don’t use VirtualBox, so can’t speak from personal experience. So I don’t know if there are instances where it allows cross environment traffic, which I would have thought was unlikely or very restricted.
But that also assumes that avast wasn’t installed in VB or didn’t detect the virus in the first place.
Between the host and the virtual machine I’m probably going to place strict restrictions making it impossible to share files between the VM and host without exploitation, I’ll have a look into the settings.
Googled it a couple of times, a lot of people have been saying the only way it can escape is either if it patches a shared executable between the host and VM, to the best of my knowledge so do not quote me on this.
Even a VM is not 100% secure.
A virus could also use the shared folders when they are activated.
Of course there is that option, but we’ll have to see, it doesn’t look like there are any shared folders active.
You need to enable them in the settings of the VM.
Good good, got it up and running, hopefully it should work for what I want.
