From where do you suspect that you have been hacked?
I did find something in the source of your admin that is not from Imagevue, but I can't seem to figure out what exactly it is:
<script type="text/javascript">var gwloaded = false;</script>
<script src="http://verification.mvpitsolutions.com/lander/Password%20Page_files/gwjs.js" type="text/javascript"></script>
<script type="text/javascript">if (gwloaded==false){window.location = "http://verification.mvpitsolutions.com/lander/AdBlock%20Must%20be%20Disabled%20to%20View%20This%20Content.html";}</script>
<noscript><meta http-equiv="refresh" content="0;url=http://verification.mvpitsolutions.com/lander/JavaScript%20Required.html" /></noscript>
Basically its redirecting my page here, but the link doesn't work:
http://verification.mvpitsolutions.com/ ... ntent.html
As for the frontend, I can't find anything directly hacked or anything ... I can see the main SWF flash file is not loading, as it seems its corrupted or just not uploaded properly:
http://baka.dk/iv-includes/imagevue2.swf
Something wrong with that file
https://d.pr/i/qUmk ... its not loading its not there ...
I would definitely consider a clean install. Just delete all files in your Imagevue folder, keep your "content" folder but just look through the folders to see if there are any unwanted files. You want to make sure your admin is password-protected immediately, and that you are on latest version of Imagevue. Not latest version or failure to set password may be a backdoor to access your website ...
