Im not familiar with Norton cleansweap so i cant really help....but If you dont have anything on the D drive that you need then go ahead and format it, it'll only take but a minute.
Then install the game fresh onto your D: drive
As for the NOCD patch, it wouldn't be tainted, It a completley seperate program and you could use it as many times as you need to.
I heard Marrowind was good but havent had the chance to try it.
