Facebook gzip_detect.php Error – Are you affected?

Today it seems as if a lot of Facebook users running Internet Explorer are receiving a strange download file request asking you to download a file called “gzip_detect.php”.

At the moment it is unclear as to what exactly this file is, and there has been no official word from Facebook, therefore I would recommend not downloading the file just in case it is virus or spyware related.

I have not received the download request myself, therefore it is hard for me to uncover exactly why this is occurring, we would greatly appreciate your feedback on the matter so that we can try to determine exactly what it is.

Please feel free to answer any of the following questions in the comments section below. Have you received this download request when using Facebook? If so, what web browser was you using? Did you download the file? If so, did it cause problems?

As we find more on the matter we will keep you up-to-date, for now I would recommend not downloading the file just-in-case and perhaps ensuring that you are running the latest version of your particular web browser.

I was getting it, tried to "save" it and the next prompt was "where do you want to save this file?" and I didn't know, so I canceled it. Could b e coincidence, but Windows update ran the same day, and I cleared my browser and it stopped. I DOUBT it is a virus or something malicious from what I read (Googled it) but it was annoying for a day or two. It popped up all the time as described above.

I have the same issued. However i clicked on download and still the error still shows up on every page I click on facebook. I tried to open it but it just gives me gibberish. I ran a virus and spywares detection program but nothing came up.
Don't really know what else to do.

I had the same problem, I have IE7 and I got rid of it by click on start, lt click on IE and rt click on internet properties, clear your browsing history.

This only started happening today for the first time. I’m on dial up (no other option) and it has severely slowed any and everything I do on Facebook and uploadig photos has been all but impossible. Whether it has anything to do with the updates I downloaded last night for Win 7 and/or for IE8, I don’t know, but I’ve about had it. I’ve been online for 2 hours and have accomplished nothing. Whatever this is, if you’re on high speed, it seems it may not be affecting what you’re doing but with dial up, it’s slowing things up for… Read more »

I started getting this after a MS automatic software update yesterday. It started just on facebook, now I'm getting it on any random pageload reguardless of the site. WTF!
I'm on a HP Touchsmart tx2 with Vista Ultimate & the latest version of IE.

I was prompted to download it as soon as I signed in to AOL…before I even opened facebook. I didn't download. Later, I opened facebook, logged in, and was prompted again. Still didn't download. Hope someone figures out WTF it's about and fixes it quick.

Just started getting it today (8/13) I run IE7 with Windows XP for the moment. Every time I change the page in FB, I get it and continue to cancel since the last thing I need is something weird on my system.

This only began today after my Norton was updated and run last night. I will not download it either. It is annoying that is for sure to have to get rid of it constantly. Hopefully, it will be resolved soon. I also use IE7

This keeps popping up on my computer too. I run AOL off of IE7 or IE8 (can't recall). I'm not downloading it, since there are so many viruses being associated with Facebook right now it's ridiculous. And Facebook seems to be running fine without the download. Still, I wish someone knew what the heck this thing was!

As soon as it started (with Facebook), any page I navigate to that has Facebook links or request for favorites (as this page does), I keep getting the message. It is very annoying and hopefully Facebook will resolve it soon, especially since I work at a place that will not allow anything but IE to be used. We use IE 8. Are there any settings in the tools menu that will aid in blocking this?

I use IE 8.0.8001.18702. Once I've logged in to Facebook, I get the download prompt for it every time I change screens. The filename I'm getting prompted for has a .gz suffix rather than a .php suffix, though I don't know if that matters. I changed from my home newsfeed to my profile and then back to news feed, and then I went from Newsfeed to one of the games, and it prompted me each time. I have not downloaded the file, as I agree with you it probably wouldn't be safe to do so until we know otherwise. If… Read more »

My theory:
Facebook has a misconfiguration in their cluster which does not allow PHP files to be intercepted on the server before the output is being sent to the client.
Furthermore; The source code cannot be read (binary) as Facebook uses a custom made compiler for their PHP-files in order for them to execute faster.

Last but not least. The issue is basically on Internet Explorer since the rest (Firefox, Safari, Chrome) handles those kind of issues the correct way – ignoring them.
