I want to share my laptop with kids and (probably idiots) friends. In order to keep it secure (without rootkits, virus, keyloggers, etc) i am planing to change my windows shell to a custom one that I have developed (works at least in w2k, I haven't tested it later). Then this shell will autostart a virtual machine (probably with virtualbox) for the guests.
The questions are:
- will this generate any drawback, especifically in video performance, specifically in games?
- will this keep the host safe?
- do you suggest other configuration (vitrualization software, operting system, or whatever)
Changing disks is not an option because I lose warranty in that case.
I know and understand that 'You just can't secure a computer to which you allow physical access', but I keep this apart because I will be close to the laptop but not watching its screen.
Thanks in advance.
