Problems Logging In

I just bought Norton Security and Backup today.  When I bought it, I created a password, but once i needed to sign in, it would say "information is required"  and make the password box red, so i just decided to try to reset my password.  When I type in the new password, i click the update button and it deletes what I wrote and makes both boxed red and says "information is required"  If someone could please help me, my computer has viruses and I really need this to work to get rid of them!!
