attach you hard drive to your husbands computer and copy all your important files.
get around the files carefully so that you may not hit the virus

I think you will only have document files to save from your hard drive
you can prevent all the executable files from clicking while you take files from you hard drive.
also install a reliable antivirus like Rising Antivirus or something else on your husband computer before connecting the hard drive into it.
if you still afraid, then first take all the important data from your hard drive to a CD or something else from the C drive of your husbands drive
Between I never save data on C drive as windows may be damaged anytime so I advise other of the same too.
