Is unTabs extension virus dangerous?

From our report of Jun 2017 · not reviewed since

Hundreds of user complaints about unTabs extension disclose the real functionality of it

UnTabs extension is a malicious browser hijacker which is far more dangerous than typical programs of the same kind.

This suspicious browser redirect virus targets Google Chrome browser and hijacks them without user's permission.

It typically changes user's default search engine to cleanserp.net or another suspicious one and also starts delivering various ads in pop-up windows or banners.

The malicious extension shows up in Chrome Extensions list, but what confuses the victims the most is that they're marked as "Installed by enterprise policy," and there is also a suspicious line next to them, saying that the extension is managed and cannot be removed and disabled.

Such signs can make the victim fall into despair and panic, however, it IS possible to remove UnTabs redirect virus, although the removal process requires some time and patience. To find out whether's you're infected with the described browser extension, please see a list of common signs of infection below.

The malicious extension is advertised as a cool tool that helps to convert Chrome tabs to a list, save them in one or more groups and restore them in one click. Unfortunately, instead of providing useful features this extension has numerous malware traits.

We must warn you that the extension is currently available on Google Web Store, so you should be very careful until Google suspends its distribution. And there are plenty of reasons why this application deserves that.

At the moment of writing this article, there were over 600 negative 1 star reviews about the extension and even more complaints about issues when trying to remove it.

This clearly creates an image of an untrustworthy piece of software that does everything to prevent users from removing it from their computers. It goes without saying that it is a typical malware behaviour.

Nevertheless, this rogue extension does not rely on the legitimate means of distribution alone to enter computers. In fact, it belongs to the group of malware which use "Add Extension to Leave" pop-ups to force users into installing it on their computers.

It also infiltrates PCs via indecent marketing methods, such as bundling . We'll elaborate on the virus distribution strategies later, but first, let's learn about what this virus does, what is the purpose of its hijack and what technique should be used for a complete unTabs removal.

UnTabs has been categorized as a potentially unwanted program, more specifically, a rogue forced extension which infiltrates computers in order to generate profit for its developers.

Once the extension is installed, it starts to inject ads, banners, interstitial advertisements, pop-ups and other commercially-based components on websites and pages that the user visits, hoping that some people would feel tempted and click on them. Unfortunately, it is hard to understand that these ads do not originate from sites the victim visits and that poses even a bigger threat to victim's privacy and security.

The developer of this shady extension will make sure the advertising is as intense as possible because it receives commissions for the traffic it manages to redirect to its promoted websites. In other words, the users engage in this so-called pay-per-click advertising strategy unknowingly.

To achieve even better results, the malware may also start tracking your browsing habits, keeping records of your search queries, visited websites, time spent there, etc. For this purpose, the extension employs tracking technologies such as cookies and web beacons.

This way, the advertiser picks ads according to victim's interests, making them harder to ignore. Over time, you may start getting the feeling that your every step online is being watched and monetized. Thus, we highly suggest performing unTabs virus removal before your browser is turned into a full-blown billboard for ads. You will get rid of the virus quickly with professionals malware-fighting software such as .

  • UnTabs virus changes homepage and new tab address to hxxp://cleanserp.net or another bogus search site that serves corrupted search results;
  • The malicious extension acts like malware and slows down the computer, making the compromised web browser lag or crash from time to time;
  • It seems to be very hard or nearly impossible to remove it;
  • The browser suddenly starts opening new tabs or windows and loading third-party advertisements in them. The victim might also notice underlined text spots in websites he visits, that display advertisements as soon as he hovers the mouse over them;
  • The infected browser can also unexpectedly redirect the user to shady websites without victim's permission to do so.

Deceptive sites using "Add Extension to Leave" pop-ups to push malicious extensions to people

unTabs virus typically reaches Chrome browsers as a result of a forced installation.

The users who regularly browse through illegal or adult content websites may be redirected to unTabs.com directly or be prompted to install the extensions via JavaScript-based "Add Extension to Leave" dialog box. Beware that you might receive a suggestion to install it after being redirected to scam sites such takeitnow.club or carrerafun.club.

Users often try canceling the installation by marking the "Prevent this page from creating additional dialogs" checkbox. But this won't work.

To exit such malicious pages and prevent unTabs installation the browser tab or the browser must be terminated via Task Manager. We'll explain the technique in more detail later on.

As we already mentioned, the malware can be installed directly from its official website, other sites that push various malicious extensions, however, it is also possible to install it along with another free program that is bundled with it. For this reason, we suggest you check software installation settings very carefully whenever you are about to install new software on your PC.

If it urges you to choose Standard or Default installation option, disobey such instruction and switch the selection to Custom or Default option instead. One or another choice gives you a possibility to review all programs and tools bundled with your chosen software and refuse to install them.

Typically, all that it takes to drop off the additional software is just to remove marks from check boxes next to permissions to install suggested additions.

How to remove unTabs extension virus

How to remove the unTabs extension virus extension

Do the browser steps in every browser and profile on the PC, then check Windows for the program that installed the extension.

  1. Step 1: Remove extensions you did not add

    In Chrome open chrome://extensions, in Edge edge://extensions, and in Firefox the menu > Extensions and themes.

    Remove every extension you do not remember adding, especially search, new tab, coupon, PDF, weather or video downloader add-ons. Check every browser and every profile, because each keeps its own list.

    If an extension has no Remove button or comes back, a browser policy holds it (see "Managed by your organization" in the procedure below). The pages are the same on Windows 11 and Windows 10.

    Chrome menu with Extensions and Manage extensions highlighted
    Chrome on Windows 11: More > Extensions > Manage extensions.

    Full procedure with screenshots: Remove a browser extension

  2. Step 2: Uninstall programs you did not mean to install

    UnTabs extension virus rarely comes alone: it is usually installed by, or together with, a free program. In Windows 11 open Settings > Apps > Installed apps, in Windows 10 Settings > Apps > Apps & features, and sort by install date.

    Uninstall every entry from the day the trouble began that you did not install on purpose, for example a download manager, a converter or a browser you never chose.

    Keep drivers and entries from Microsoft, Intel, AMD, NVIDIA or your PC's maker unless you are sure.

  3. Step 3: Reset the browser

    A reset removes what the steps above could miss:

    • changed start pages
    • site permissions
    • hidden settings

    In Chrome open Settings > Reset settings > Restore settings to their original defaults; in Edge Settings > Reset settings; in Firefox Help > More troubleshooting information > Refresh Firefox.

    Tip: Bookmarks and saved passwords stay, while extensions are turned off and the search engine and start page return to the defaults.

    Reset every browser on the PC, including Edge, which Windows 11 and Windows 10 always have.

    Chrome Settings page with the Reset settings section open
    Chrome on Windows 11: Settings > Reset settings.

    Full procedure with screenshots: Reset a browser and fix a hijacked search engine

  4. Step 4: Scan the PC, then run the offline scan

    A scan finds the parts of unTabs extension virus that the manual steps cannot see. In Windows Security > Virus & threat protection > Scan options, start a Full scan and quarantine what it reports.

    Follow it with Microsoft Defender Antivirus (offline scan) > Scan now, which restarts the PC and checks the disk while Windows and the malware are not running.

    It takes about 15 minutes and works the same in Windows 11 and Windows 10. If either scan finds something, run the full scan again after removal until it comes back clean.

    Windows Security Scan options with Microsoft Defender Antivirus offline scan selected
    Windows 11: Windows Security > Virus & threat protection > Scan options.

Questions about unTabs extension virus

How do I stop cleanserp.net from opening?

Find and remove whatever opens it. Start with the browser's extensions page and remove anything you do not remember adding. Next, open the notification settings and take away permission from sites you do not recognise.

Then check Settings > Apps > Installed apps for programs added around the day the redirects began, and uninstall those. Restart the browser and test a few links after each step.

If cleanserp.net still appears, reset the browser, which restores the default search engine, start page and permissions without deleting bookmarks or saved passwords. Redirects that survive a reset in every browser point to a program in Windows, and a full scan is the next step.

Should I worry about redirects to cleanserp.net?

Worry less about cleanserp.net itself and more about what keeps sending you there. A single redirect from a free streaming or download site is normal and harmless once the tab is closed.

Repeated redirects on sites that used to work fine mean something in the browser or in Windows changed, often an extension or program installed alongside other software. It may also collect the pages you visit. Remove the cause with the steps in this guide, and do not act on anything the redirected pages ask:

  • no Allow clicks
  • no downloads
  • no calls

If you already did one of those, the matching section of this guide explains what to do next.

Why does unTabs extension virus show me ads?

Because that is its whole purpose. UnTabs extension virus is an adware extension, and its operators are paid for every ad it displays and every click it gets. In this case the ads take the form of redirects through ad pages.

They are chosen by ad networks that accept almost any advertiser, which is why so many look like warnings or prizes. The ads are not a sign that your PC is broken or infected with something worse; they are a sign that something on it, or in the browser, has permission to advertise. Removing that permission or program stops them.

Do I have to clean every browser?

Yes, if you use more than one. We saw unTabs extension virus in Chrome, Edge and Firefox, and each browser keeps its own extensions, notification permissions and settings. Chrome and Edge share the same extension format, so one installer can add the same adware to both, while Firefox has its own add-ons.

Check every browser on the PC, including ones you rarely open. If you sync a browser with an account, clean it while signed in, so that the removal reaches your other computers rather than the adware returning from them.

How do I know the ads come from unTabs extension virus?

Look for redirects to cleanserp.net. That is the trace unTabs extension virus leaves, and it shows up as redirects through ad pages. Ads that appear on every site, including ones that never carried ads before, point to something on your PC or in the browser rather than to the sites themselves.

A quick test is a private window, where extensions are off by default: if the ads disappear there, an extension is responsible. If they appear even with the browser closed, the source is a notification permission or a program in Windows.

I clicked on one of the ads. Am I infected?

Probably not. Clicking an ad usually only opens a page, and a page cannot install programs on an up-to-date Windows PC without your help.

You are at risk only if you then downloaded and ran a file, allowed notifications, entered card or login details, or called a phone number shown on the page. Delete any download and run a full and offline scan.

Change passwords you typed, from a clean device. Call your bank if you gave card details. If you called a number or allowed remote access, see the next question.

Why didn't my antivirus catch unTabs extension virus?

Many security products do not block adware or notification sites by default, because users often agreed to them, even through a misleading prompt. Notification spam installs nothing at all, so there is no file to detect.

In Windows 11 you can make Microsoft Defender block potentially unwanted apps: open Windows Security > App & browser control > Reputation-based protection settings and turn on Potentially unwanted app blocking. If notifications caused the pop-ups, no scanner will report them; the fix is in the browser's site settings.

Can adware slow down my PC?

Yes. Adware runs in the background, loads ad scripts, opens extra tabs and contacts its servers, all of which use processor time, memory and bandwidth. Ad-heavy extensions also slow down every page, because they inspect and change it before you see it.

The effect is strongest on older PCs and when several adware programs arrived together. After removal, restart the PC and check Task Manager for anything still using a lot of resources that you do not recognise. Speed usually returns to normal once the ads stop.

Does adware steal passwords?

Ordinary adware is built to show ads, not to steal logins, and most of it never touches saved passwords. The line is blurry, though. Extensions that can read every page could capture what you type, and adware ads sometimes lead to phishing pages that ask for passwords directly.

If you entered credentials on a page reached through an ad, change that password from a clean device and turn on two-step verification. Otherwise, removing adware extension and clearing cookies is usually enough.

Will Fortect remove unTabs extension virus?

Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.

For unTabs extension virus, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.

Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
