Omar007 on "Malware Exploit Blackhole on my site. Don't know how to remove it"

Hello,

I seem to have Malware issues with my website sinvest.co.uk (Disclaimer page) sinvest.co.uk/main (WordPress installation. I've scan the website with Sucuri which states "javascript malware" "exploitkitblackhole1?v57" ect. Though It states the Malware is on multiple pages (essentially all of them), I cant seems to find where in the source code they are located. At this point I have no clue how to clean the site.

I checked Htlacess file as well as style.css and found nothing that I would suspect (though i'm no expert).

Please could someone suggest solution for this specific Malware
