My question is how does one completely delete Facebook? My computer became infected on Facebook and I want off permanently.
FB does not reside on your pc. You can disable your account but the data will remain on their servers for ever. I would think removing one pic at a time would be effective.
As far as your pc go to the options - security tab in your browser and delete all cookies and history related to FB. I would bet you would have to delete ALL your history and cookies to truly remove it from your browser.
Look under accounts
There are two options, deactivate which means it still exist but anyone contacting you via facebook will get a message that your account has been deactivated.
Second is to delete. It is complicated but they do give you the option. Warning. It takes 14 days to become official. If you sign in before the 14 day are up, the account is put back into service (I think this is to keep your friends from hacking into your account and deleting it)
I recently deactivated my account (after removing all my notes, photos and comments). I have not decided if I am going to make it permanent or not.
I will admit I missed it for a day or two but now not so much.
