I would to start testing malware and there is a few things i want to check first. Im running XP in a VM on a old computer. Is it possible for a piece of malware to infect anyone else on my network, for example if a worm if its in a VM? Second question is I've read its possible for malware to change router settings, open ports etc. Is this possible and if it is how common would it be? I have my router password protected.
