    I’ve been using Usenet for downloading for many years. I JUST RECENTLY BEGAN USING SUPERNZB. Here is my problem: For about a year now I have been getting a lot of downloads with virus .exe files that are no good. They have a video file of the proper size and common extension (like AVI, FLV, etc) but are unplayable. Nothing I’ve tried plays them, including VLC which normally plays anything.
    The common denominator is they each have an accompanying text file that has the following content : “If you get the error”: “Can’t play the file.” “Install the codecs from the /Codec/ Directory.” Enjoy the movie!!
    The .txt file is sometimes but not always named “If_you_get_error.txt” and there is an accompanying .exe file as well, usually named codec.exe….THIS ONE IS THE ONE YOU DO NOT WANT TO OPEN!!!!!
    The movies are all different sizes, they seem to be between 700 and 1000 MB. The accompanying .exe tends to be between 220 and 230 kb. Even the If_you_get_error.txt file varies in size, although it tends to be 137 bytes or less.

    It seems that about 50 % of the downloads are of such. I don’t have unlimited time, so this is not a good thing especially since it is ongoing.
    Incidentally my virus checker misses them and the file checker in Supernzb says only that all files are present , or words to that effect.

    Has anyone else encountered this problem? Any solutions? Any way to tell supernzb not to download these spam file movies?

    Where are you getting your NZB files from? If you use a curated site, you will never get bogus NZBs. Try: http://nzbplanet.net/

      have had problems on “Binsearch” and UsenetServer.

      • Matt says:

        Binsearch’s listings are automated, so bad NZBs can sneak in there. UsenetServer, like every other Usenet company, does not check files to make sure they are real. There’s a lot of trash on Usenet, and always has been. But it is easily avoided by using an NZB site with curated listings.

        • Vincent jura says:

          So nzbplanet has “curated” NZB postings? I assume this means the postings on this server are actually managed by NZBPlanet ? (as in screened for invalid files)

            You would have to ask them, but I think their user community uploads the NZBs. However they do it, the results are excellent.
