Norton Defs/System Restore

I was browsing on here and I read some posts where people have used sytem restore. I know its not the best thing to do.

However, if one does initate a system restore, how does that effect the Norton Product?

Example- all defs are up to date 3/24/09 and one does a system restore to 3/19/09. Do you lose all your defs and updates to Norton that have occured after 3/19/09?
