Stefan, note that I said that NOD32 did NOT indicate any problems when I tried the link yesterday. While it is certainly possible that the problem it indicated when I first tried the link on the day your original post appeared was a false positive, it is also possible that it was due to an infected third party ad server that was serving one of the many popups which appeared at that time, which were subsequently removed. That kind of thing has happened now and then even to a number of very large and well known sites whose reputability is beyond reproach, such as some major newspaper sites.
Regarding codec packs, I've read of many instances where installing completely legitimate codec packs can result in conflicts with existing installed codecs that may be used by video and audio editing programs. I happen to use such programs.
Finally, let me make sure it is entirely clear that no one is suggesting in any way that you may have either intentionally or negligently posted a link to malware. I was just reporting the facts of what happened when I clicked on the link. Implicit in those facts is that it would be prudent for you and others to exercise caution. One way of exercising caution is what I mentioned that I did yesterday, creating an image of the contents of my hard drive, using a drive imaging program, that I could revert to if necessary.
