My jailbroke iphone won't sync with itunes after update 6.1.3?

My iphone won't sync with itunes on the computer i had removed everything from my iphone and made it out like a new iphone now i can't sync to itunes meaning i can't use my phone

Added (1). It was syncing before it just happened as soon as i wiped my phone and updated it

Try turing off antivirus, sometime it blockes the sync
