I use a Lubuntu 12.04 installed inside a VM to browse less than safe websites with Chrome. I would like to know of the relevant security risks this setup poses to my home network. I do not store anything on the VM itself, so I couldn't care less if it's compromised. But I do care if malware spreads to other parts of my home network. I have 2 Windows 7 PC's and 2 Macs.
