help with Win 32 virus can’t start my computer

I have the Win32 virus on my computer, had to shut down computer but then it would not reboot not even in safe mode. I need the files off of this computer. What would happen if I take the hard drive out and connect it to another computer will Win32 virus attack the computer that I connect to? Will I be able to safely back-up my files from the hard drive without save the virus on my USB?
