Can't get into Facebook

Hello,
when I put my name in to go to fb i get a large box say lets check your device for malicious software... i click on contiune and Norton pops up and says unsafe. Now before I clicked on contiue , I update the computer, with Norton, did a threat check and scanned and they said no threats , everything looked good. this has been a week of this, then I went to start a new account and I get the same thing, same message. was I hacked, or what?
