I uploaded an image called “PastorAdvert.jpg” to the church website, but every time I tried to view it using FF or IE I got redirected to this url:
http://127.0.0.1:1040/clear.cgi?
which downloaded a 10×10 px clear image.
It appears that ZoneAlarm was tagging the image as adware, simply because the image was named “…Advert.jpg”. I renamed the file to “Pastor.jpg” and it worked perfectly!
Oh well, another good use of 20 mins of my time!
