I can acces via the IP but the page does not load with images, and when I click on the page for another link it gives me the same error as above.

I've done what you said and still didn't work out.

Do a malware check with some malware scan programs.
You need to scan with all programs because each program detects different malware.
Make sure that you update each program to get the latest version of the database before doing a scan.

Something is really fucking up my PC, I do have ad-aware but it does not let me auto update. When I try to manual update my spyware database, it won't let me download it... http://download.lavasoft.com/public/core.excluded.aawdef.zip

Same goes for all of those links you gave me above (except ad-aware), it gives me: "Server not found Firefox can't find the server at www.malwarebytes.org."

But according to my other friends, the website is just up...

Such a behavior is a strong indication that you are infected.

If you can't fix it with the above listed scanners then you need to ask advice on one of the forums that specialize in malware removal mentioned in the Popups_not_blocked article.

All fixed now, I've downloaded malware and spybot on my laptop and used an usb-stick to install them here.

I found 5 trojans named with "DNS changer". Now randomc is working, my ad-aware is also auto updating.

Thanks for your help! Is there anything else for me to worry at the moment? I mainly use AVG and Ad-aware untill I ran into this problem...
