 * Hello there,
 * Today I have noticed that when I open my website an automatic html file called“
   fallback.html” is downloaded.
 * The file comes from the following website:
 * `d341y4dudrfjax.cloudfront.net`
 * When I open it, there is an image from instagram that include different hashtags.
 * Do you know what it could be and how to fix this?
 * Thanks in advance
    Bliss07

 * That’s not part of WordPress by default, try deactivating your plugins to explore
   whether any could be responsible.

 * My clients just had the same thing on their site. We think it may be malware 
   related to an advert that was being served on their site by a third party.
 * Can I ask, do you have adverts on your website too?

 * Hello Ceekay,
 * I was able to fix that issue by following the suggestion of Andrew.
 * I have deactivated few plugins, especially the ones that I have installed recently
   and the automatic html download has disappeared.
 * I believe that the issue is not caused by any advertisement but from some plugin.
 * Hope that helps.

 * Hello,
 * I don’t own any website and don’t use WordPress, but I have the same problem.
   Regularly, while I didn’t do anything in particular, my PC attempts to download
   the exact same file as described by Bliss07. I don’t think I have any unusual
   plugin on Firefox either. What should I do?

 * Hi,
    Oneyr and i Seem to be having the same problem. A HTML file call “fallback.
   html”, keeps downloading from a site called:” `d341y4dudrfjax.cloudfront.net`
   This opens without my involvement and was wondering if anyone knows how to fix
   the problem.

   the plugin that you think was responsible.

 * The first plugin that I have deactivated was “Contact Form 7”. However, afterwards
   I have deleted all the unused plugins, which they were all related to social 
   networks and the issue did not occur anymore.
