O.K.
I can now proof and reproduce what is going on.
The webserver, a PHP script, a htaccess file or similiar configuration file (depends on webserver, OS and configuration) is redirecting the user using a 302 redirect to other websites.
Proof:
http://cloud.kab-s.de/public.php?service=files&t=5e6ec7531188453cfe77f89c3d72673dIn the lower right corner you can identify the answer from host "adrenalinex.co.uk" as a 302 redirect by the "Location:" tag. It's redirecting you to some strange website where traffic management is handled and the user is redirected again a few times to obfuscate what's going on. After a few seconds the user is redirected to a landing page with some randome ads or maleware.
How to reproduce (
DON'T DO THAT IF YOU DON'T KNOW WHAT YOU DO):
1. Logout from this forum
2. Close any tabs in your browser that are related to AX.
3. Clear your cookies as well as your browser's cache.
4. Restart your router for a new IP (This won't work with static IPs)
5. Go to google.de (or the correspondig google website for your country)
6. Search for "adrenalin x"
7. Click on "AdrenalineX Racing - play.adrenalinex.co.uk:7777"
8. I was redirected with a chance of about 90%. (From Germany with Firefox)
It appears that you have to match certain conditions, because I was unable to reproduce this in Chrome. I've logged all the traffic using smartsniff so I'm relatively sure that this is not related to adware.
If you (Admins) are sure that this is not related to a security breach on your side, you should contact your hoster right away. If I were you I would also think about changing your hosting provider. If any assistance is required me and I think alos the rest of the RSD-Clan are willing to help you out.
