This raises a question: Is anti-virus software necessary in a virtual machine? I don't have AV installed on my WinXP VM because I created a clean back-up copy of the .vdi file immediately after I installed WinXP on VirtualBox. I figure I can replace an infected .vdi file quite easily if I have to.
I like to keep the VM as stripped-down as possible so I can boot into it, run what I have to run, and exit quickly. This also keeps the .vdi's footprint small. The same policy applies to patches and security updates. I installed SP3, but nothing beyond that.
So far I haven't seen any overt signs of any virus infections on my unprotected system, although I actually haven't run any scans to verify that it's clean. What are people's thoughts on this?
