This is what Chrome told me:

Danger: Malware Ahead! Google Chrome has blocked access to this page on torrentfreak.com. Content from ox-d.traffiqexchange.com, a known malware distributor, has been inserted into this web page. Visiting this page now is very likely to infect your computer with malware.

So it's one of their advertisers. Main problem with 3rd party ad networks =/ Hope they sort it out.

For what it's worth, torrentfreak is pretty clean.

Either adblock or ghostery is blocking that ad network, then.

What you need is NoScript ;-)

Well, you can roll the dice. Depending on what OS you're on, that dice may be weighted differently...
