Re: OriginWebHelperService.exe stopped working
@VermilionSphere If you have the helper service enabled, it will keep running even after you exit Origin. (I don't think it will start on its own if Origin is never open, but I haven't tested.) To disable it, open Origin, hover over your username, and select Application Settings. Under Application (the first header), scroll down to start-up options and disable the helper service. You may then need to manually kill the process in the Task Manager or restart your computer to get rid of it though.
For the Sims 3 issue, try clearing Internet Explorer's cache. Even if you never use it, the game and launcher do for some purposes. Be sure to uncheck the box to preserve data for favorite sites.
