I want to start using some BH tools but a little worried about some of the sites these tools target (virus/maleware etc ...) I read in another thread that i should use VMware? do you agree? If yes, can you just explain what VMware is? as i understand it, its a version of my OS that runs within my main OS? so that if i run any BH tools and get spanked with a virus/maleware it only effects the OS system im running in VMware? Correct? If yes, Im running windows 7 64bit. Is VMware free? can anyone advise me which version i should download? And once installed how do i install a copy of windows into it? or does the install of VMware do this for me from my main OS?
