I experienced a similar thing not too long ago. Actually entire folders got blocked on my hobby site mameworld.net.

I placed all of our sponsors banner images in a folder called "sponsors" and got several mails from people that none of the images showed. Seems like the word "sponsors" is being bocked by "ad aware" type programs, too.

Quite silly in our case since our ads are actually 100% targeted, hand picked and a help for our visitors who are looking for quality arcade products...ah well, now the folder is calles "pics" and all is fine :)
