Site is giving malware message to users
 

I have attached the malware screenshot that one of my users has sent me. Anyone know whats going on or whats causing this, or better yet, how to fix what ever has gone wrong.

Try downloading the files form your customer area at vB.com, for the exact version you are using, and upload those files to your server, allowing overwrite, then test again.

I bet it's coming from one of your third party adverts.

I don't see any of that in the Sucuri report, http://sitecheck.sucuri.net/results/hanging-out.net

I dont run any advertisements at all.

You have it set where you must be logged in to view the board? Must be hell on your SEO.

Even at that, look here - you have alot of 404 errors AND third party links abound.

If you click on any link on the site the address bar for FF in the lower left hand corner briefly show that is transfering data from komedes.at....

That's one of the third party links in your pageload waterfall i linked you to.

Your site has been infected somehow, this could be from an outdated script or just a poorly coded plugin.
I'd suggest you upgrade your forum, upgrade your plugins and scan your public styles for any malware code listed in the report by the OP.

I dont do any SEO. Im an organic chemist, so honestly I dont have any idea what this means. I can tell its not good, but how to I clean it up.
