Ok, so I downloaded a corrupt file that I should not have and need to reinstall mavericks. I have 2 administrative accounts on my mbp and the account that I dl'd the file to was my main account. I cannot log into that account because of the corrupt file (spinning rainbow pinwheel). I'd like to delete that corrupt file from my other admin account and save the rest of the desktop to an external hd and do a clean install of mavericks and start fresh. Is this possible? as a last resort I have a time machine backup that was last saved about 3 months ago but I'd prefer not to go that route as I'd lose some files and work. Thanks for your help
