Oh, yes and your jQuery code version is vulnerable to happyWorm infection. jquery - 2.1.4 : (active1)…
IP address has been reported many times for Open Proxy detection and has been blacklisted as such!
Link to -http://g.symcd.com/ has been blocked for me by a script blocker.

We cannot de-block your website as we are volunteers with some relevant volunteer website security knowledge.
De-blocking can only be performed by Avast Team Members, and we here are not.
Wait for an Avast Team Member with a reaction or report to avast dot com base.
