Is this a virus or...?

Date Published: 08/23/2013 12:35 AM


During the past few hours this has occurred two times and it's never happened before. I'm never at the computer when this happens so I have no idea what's going on.

When I go away from my computer, while leaving Google Chrome open, for 30+ minutes I find that there are four new tabs all with empty pages opened. The url bar always has entered in it.

I've done a full scan of my computer with Microsoft Security Essentials (Windows Defender since I'm running Windows 8) and it turned up nothing. When I try googling the link in the paragraph above all I get is a bunch of ranking websites and a few Japanese links.

As far as I can remember, the only major thing that I've done before this started happening, is installing LaTeX. I downloaded the first link on this page which was given to me by the official LaTeX site. I doubt this has anything to do with the problem but that's it.

    Sorry I don't have an answer for you, but I do have the same issue (although my 4 tabs pop open at startup)

    I've not added anything to my system, and run Norton (which I hope is doing it's job), so I'm pretty baffled as well!

    Anyone any ideas?

    Yeah, got the same thing here oddly enough - just started happening today, without installing anything new :-/
    The icon at those pages are all a facebook icon, so perhaps somehow facebook is doing it? hmm

    GOT IT! (And you're so close HC)

    Having spent a good part of the afternoon deleting stuff, scanning, etc, it's the FB part of the FBCDN addresses (as they are different in each window) that gives it away:

    Uninstall the FaceBook messaging 'app' from your programmes and Vola, its gone!

    Thank goodness for that... And Facebook really need to sort their act out.

    WOW thank you guys for this awesome site!! lol i was so confused..

    tytalus, ive always used FB messanger but i will uninstall and see how it goes! :D thank you!

    All I can say is that it worked for me, and I've been using FB messenger for ages as well. At least it's something easy to remove without dodgy 3rd party software, won't leave your machine venerable, easy to re-install and hopefully the problem is a one off and won't re-appear.

    Would be nice to know if I was lucky, or it really does work, though :)

    This happened to me too and since deleting facebook messenger it hasn't happened, however, i have read on various different sites that this is a virus that is temporarily dealt with by deleting facebook messenger but it leaves harmful files on your computer that can't be picked up by anti virus software, can anyone tell me if this is true or is it a bunch of people on the internet trying to cause a panic over nothing ?

    I "had" a similar problem but seemed to have resolved it "without" the removal of FB Messenger. When the computer booted, my Chrome browser would automatically open with these 6 URLâs in it:







    I am not really sure what the cause of this was except that I was trying to send my friend a URL to my server page using FB Messenger and FB blocked it. I think I tried 6 times hence the 6 instances above. That is when this issue started occurring so I think was the cause.

    I download Malwarebytes Anti-Malware (Trial) from

    Database version: v2013.09.03.08

    Windows 7 Service Pack 1 x64 NTFS
    Internet Explorer 10.0.9200.16660
    MBAM-log-2013-09-04 (10-33-40).txt

    Scan type: Quick scan
    Scan options enabled: Memory | Startup | Registry | File System | Heuristics/Extra | Heuristics/Shuriken | PUP | PUM
    Scan options disabled: P2P
    Objects scanned: 248474
    Time elapsed: 1 minute(s), 49 second(s)

    Registry Keys Detected: 1
    HKCRAppID{C26644C4-2A12-4CA6-8F2E-0EDE6CF018F3} (PUP.Optional.Delta.A) -> No action taken.
    Files Detected: 0
    (No malicious items detected)


    The culprit was a registry key âPUP.Optional.Delta.Aâ:
    Windows Registry Editor Version 5.00
    "sp_name"="Delta Search"

    I let Malwarebytes Anti-Malware delete the Reg Key and now my problem seems to have vanished.

    Hope this helps.

    I stopped having this problem once I stopped opening the facebook messenger program on my computer. I tested this even and just as soon as messenger opened, I had six tabs on my firefox browser and I have also stopped getting the random tab opening on my chrome. I haven't stopped using facebook messenger as I am using it from my browser instead.

    I have also gone as far as uninstalling the program so that it wouldn't be opened accidentally sometime when I start up my computer. I scanned and scanned my computer and everything came up clean. It is in the messenger program itself.

    Hope this helps someone.

    This fact came to happen here too.
    unfortunatelly i had to uninstall the messenger...
    even if we don't know what's happening here until now, it's better to keep a posture of defense against this possible threat.

    simple, Its FB messenger that is the culprit (the address quoted is related to pictures of your friends list). Just uninstall it and fill in the feedback form like I have. They'll so fix it.

    Removed messenger and all fixed here

    I always used FB Messenger, and never had this kind of problem.
    Today, it happened twice. The only thing that has changed, is that my internet service is unstable.

    So, if I would guess, FB Messenger is calling these pages at every moment, but only when things goes wrong (internet stops working) the popups may appear (as the error response was not what FB was expecting for).

    So, if this happens to you on boot, maybe FB is loading before your PC connects to the internet. Just a bug inside the FB Messenger.

    That said, definetly, not a virus.

    About the addresses:
    - They are links to CDNs around the world (one from Tucows and the other from the "MARKMONITOR INC", probably in name of FB itself)
    - CDN stands for:
    - So, you can think of "hellocdn.html?v=1" a little "connection test", just like a "ping". Something facebook messenges does once in a while to see if its network is working properly. In my case, it wasn't, so I got these popups.

    I've had this problem for a couple of days now, and I have reported it to facebook. I really like the facebook messenger app for windows and I don't want to remove it so I hope they fix it. And I think they should start updating it because they don't seem to care about the app at all.
  • Jane posted this on 12/25/2013 at 10:16 PM

    John Doe, I get what you have explained. Because im getting the pop ups plus i've been having issues with my fb messenger app. Has your app been restored? How do i fix it?

    As per C22600, I'm DL'ding Malwarebytes for the 1st time in awhile, to scan for and delete the bugs within this app--I'll keep using Messenger if it ceases entirely.
    Before I found this page, I went into Chrome and blocked popups from this site, and am about to go back in and use wildcards to block any popups from either 'fbcdn' or 'akamai'.
