I'm thinking that your problem is not with the program or your subscription or virus .. but that it's just your use of 2 monitors and how you've configured that with different monitors. I still feel you should try to get your nvidia card configuration and one monitor working properly before going into other avenues of troubleshooting. You don't lose anything by troubleshooting with one monitor in the long run. You can always ( once problem is solved ) just add another monitor. So I would stick with one monitor and make sure all is happy with your one monitor at least, before going off into other areas. I'm sure there are very smart people here with CS6 and the time to help you with making sure your ONE monitor setup is correct for the resolution MONITOR you are using.
I personally have gone through some monitor and graphic card driver HELL in the past and right now I only have one monitor and it's 1440 x 900 so I don't feel I can personally help you with the Nvidia settings you need for one monitor at this point. I'm sure someone else will help you with that part of the problem soon... at least eliminate it as a possible contributor to your problem if nothing else.
Good luck !
