security of virtual linux guest on windows host

hi. if i install a linux guest on windows host in a virtualised environment (qemu for example), will any malware that might already exist on the windows host have access to the virtualised linux, or will the new virtualised environment be safe?

for example, if the host have some malware that i am not aware of that tracks keystrokes, will any password i type in a browser in the virtualised linux be vulnerable?

thanks
