Itunes Shows Error 2005

Hello everybody

First of all when i want to restore my phone with new restore it shows for me iTunes ERROR 2005, Then i tried to many popular solutions like am updated the last version of iTunes and update also my PC, I tried many different cables, then also i tried another PC. In some website said turn OFF the antivirus and firewall , but this error still the same.

And also i do this before i start restore (Press and hold both the sleep/wake and the Home button until the screen goes black. Release the sleep/wake button but continue holding the Home button for about 20 seconds. After about 20 seconds, you should see your iPhone pop up in iTunes in recovery mode, asking for a restore. Your iPhone LCD should remain black).

if anyone can help me to solve this problem please help me

Thank you

Its still shows this error
