Hi,

I want to be infecting a Windows 7 guest VM on my Windows 10 Host PC. Can anyone advise me on what settings to choose for networking? Can a virus spread from the Guest to the Host? In terms of what viruses, nothing too sinister. Bonzi Buddy, and just adware and fake AVs. There will be no trojans or ransomware or anything of the like.

Thanks,

If there is a network between the host and the guest and the virus is network-aware, then it could get onto your host from your guest. The easy solution is to not have a network, or at least "disconnect" the network, before running your viruses.
