Safari hangs under Mavericks.
Is there a way to uninstall and re-install Safari? After installing Mavericks, Safari doesn't work anymore. THere is an unknown tab that keeps appearing, and I can't delete it. In the primary tab, where I have my home page, none of the links are active. If I click on them, the color pinwheel appears and just keeps spinning. Is it possible I have picked up some virus? My desktop iMac shows NONE of these symptoms, but my laptop Macbook pro is suffering.
MacBook Pro, OS X Mavericks (10.9)
