Remove lko.jafyzfyu.com from Firefox, Chrome and Internet Explorer

This page shows how to remove lko.jafyzfyu.com from Mozilla Firefox, Google Chrome and Internet Explorer.

Does this sound familiar? You see lko.jafyzfyu.com in your web browser’s statusbar while browsing sites that normally don’t load any content from third party domains. Perhaps the lko.jafyzfyu.com domain appear when performing a search at the Google search engine?

Here’s a screen capture of lko.jafyzfyu.com when it showed up on my machine in the network log:

lko.jafyzfyu.com connection

The following are some of the status bar messages you may see in your browser’s statusbar:

  • Waiting for lko.jafyzfyu.com…
  • Transferring data from lko.jafyzfyu.com…
  • Looking up lko.jafyzfyu.com…
  • Read lko.jafyzfyu.com
  • Connected to lko.jafyzfyu.com…

Does this sound like your story, you probably have some potentially unwanted program installed on your machine that makes the lko.jafyzfyu.com domain appear in your browser. So don’t send angry emails to the web site you were browsing, they are presumably not responsible for the lko.jafyzfyu.com status bar messages. The potentially unwanted program on your system is. I’ll do my best to help you remove the lko.jafyzfyu.com message in this blog post.

For those that are new to the blog: Some time ago I dedicated some of my lab computers and knowingly installed some potentially unwanted programs on them. Since then I have been following the behaviour on these computers to see what kinds of advertisements that are displayed. I’m also looking on other interesting things such as if the potentially unwanted program auto-updates, or if it downloads and installs additional potentially unwanted programs on the machines. I first found the lko.jafyzfyu.com in Mozilla Firefox’s status bar on one of these lab computers.

lko.jafyzfyu.com resolves to the IP address.

So, how do you remove lko.jafyzfyu.com from your browser? On the machine where lko.jafyzfyu.com showed up in the status bar I had installed. I removed them with FreeFixer and that stopped the browser from loading data from lko.jafyzfyu.com.

The problem with status bar messages such as this one is that it can be caused by many variants of potentially unwanted programs, not just the potentially unwanted program that’s installed on my system. I think that potentially unwanted programs such as SpeedChecker, WebWaltz, PriceFountain and YTDownloader can also be responsible for lko.jafyzfyu.com appearing in the browser. And there are probably other variants too. This makes it impossible to say exactly what you need to remove to stop the status bar messages.

Anyway, here’s my suggestion for the lko.jafyzfyu.com removal:

The first thing I would do to remove lko.jafyzfyu.com is to examine the programs installed on the machine, by opening the “Uninstall programs” dialog. You can reach this dialog from the Windows Control Panel. If you are using one of the more recent versions of Windows you can just type in “uninstall” in the Control Panel’s search field to find that dialog:
Uninstall a program search

Click on the “Uninstall a program” link and the Uninstall programs dialog will open up:
Uninstall a program dialog

Do you see something strange-looking listed there or something that you don’t remember installing? Tip: Sort on the “Installed On” column to see if something was installed about the same time as you started getting the lko.jafyzfyu.com status bar messages.

Then you can examine you browser add-ons. Potentially unwanted program often show up under the add-ons menu in Firefox, Chrome, Internet Explorer or Safari. Is there anything that looks suspicious? Something that you don’t remember installing?
Firefox add-ons manager

I think you will be able to find and uninstall the potentially unwanted program with the steps outlined above, but in case that did not work you can try the FreeFixer removal tool to identify and remove the potentially unwanted program. FreeFixer is a freeware tool that I’ve developed since 2006. Freefixer is a tool designed to manually identify and uninstall unwanted software. When you’ve tracked down the unwanted files you can simply tick a checkbox and click on the Fix button to remove the unwanted file.

FreeFixer’s removal feature is not locked like many other removal tools out there. It won’t require you to pay for the program just when you are about to remove the unwanted files.

And if you’re having a hard time deciding if a file is legit or potentially unwanted in the FreeFixer scan result, click on the More Info link for the file. That will open up a web page which contains more details about the file. On that web page, check out the VirusTotal report which can be very useful:
