"i have some programs/drivers i dont want to have to reinstall "
No - if you reformat and reinstall windows, you will need to reinstall all the programs and drivers that aren't in windows itself.
If you want to do a "factory restore" and your computer has the facility to do that, then that's a slightly different thing to simply re-installing windows - so what make model system do you have, and what restore or other system CDs do you have?
What do you use for emails? - yes you can save emails and data and address lists - but how you do so depends what program you are using for emails.
But before you do that - what virus do you have that can't be removed - that would be unusual - maybe we can help with that and save you the reinstall hassle.
