then passwords you have already set up for certain websites will have to be re-setup each time you log on
That happens every time Norton does a clean up on my computer. I downloaded a program called Roboform that stores all my logon names and passwords. When I enter a site that needs logon info, Roboform pops up and fills in the form. The only password I need to remember is the one to open Roboform. I would guess that there are other similar programs out there also.
