Remove ut.performax.cz From Your Browser

This page shows how to remove ut.performax.cz from Mozilla Firefox, Google Chrome and Internet Explorer.

Did you just interrupt your work because you noticed ut.performax.cz in your browser's status bar? You are not alone. I also got the ut.performax.cz status bar message while browsing. Please read on...

Here's how the ut.performax.cz statusbar message looked like when I got it on my machine:

ut.performax.cz in the status bar

I noticed ut.performax.cz in the status bar and the network log while I was browsing a site that I know does not load or link to any content outside of the site.

Here are some of the statusbar messages you may see in your browser's status bar:

If you also see this on your system, you almost certainly have some potentially unwanted program installed on your machine that makes the ut.performax.cz domain appear in your browser. Contacting the owner of the site you were browsing would be a waste of time. They are not responsible for the ut.performax.cz status bar notifications.

I'll do my best to help you remove the ut.performax.cz message in this blog post.

I found ut.performax.cz on one of the lab computers where I have some potentially unwanted programs running. I've talked about this in some of the previous blog posts. The potentially unwanted programs was installed on purpose, and from time to time I check if something new has appeared, such as pop-up windows, new tabs in the browsers, injected ads on website that usually don't show advertisements, or if some new files have been saved to the hard-drive.

So, how do you remove ut.performax.cz from your web browser? On the machine where ut.performax.cz showed up in the statusbar I had a few programs installed, which are often referred to as "potentially unwanted". I removed them with FreeFixer and that stopped the web browser from loading data from ut.performax.cz.

The problem with status bar notifications such as this one is that it can be caused by many variants of potentially unwanted programs, not just the potentially unwanted program running on my computer. This makes it impossible to say exactly what you need to remove to stop the statusbar messages.

Anyway, here's my suggestion for the ut.performax.cz removal:

The first thing I would do to remove ut.performax.cz is to examine the programs installed on the machine, by opening the "Uninstall programs" dialog. You can find 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:

Do you see something shady listed there or something that you don't remember installing? Tip: Sort on the "Installed On" column to see if some program was installed about the same time as you started seeing the ut.performax.cz status bar messages.

Then you can examine your browser add-ons. Potentially unwanted programs often show up under the add-ons menu in Google Chrome, Mozilla Firefox, Internet Explorer, Safari or Opera. Is there something that looks suspicious? Something that you don't remember installing?

Please also test to disable the web browser proxy and the system proxy on your system. Did that stop the connections to ut.performax.cz?

I think you will be able to identify and remove 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 started develop many years ago. Freefixer is a tool built to manually find and remove 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 crippled like many other removal tools out there. It won't require you to pay a fee just when you are about to remove the unwanted files.

And if you're having difficulties deciding if a file is clean or potentially unwanted in the FreeFixer scan report, click on the More Info link for the file. That will open up your web browser with a page which contains more details about the file. On that web page, check out the VirusTotal report which can be quite useful:

As a last resort, if the above steps did not solve the ut.performax.cz problem, you can block ut.performax.cz in the Windows HOSTS file.
