Cleanserp is another fake “privacy-focused” search engine developed to gain ad-revenue is a potentially unwanted application that enters your machine via a deceptive distribution tactic called software bundling is a browser-hijacking application that allegedly “respects your privacy.” However, this potentially unwanted program was found being bundled along with such adware apps like Untabs for Google Chrome or Mozilla Firefox web browsers. Quite often, browser-hijacking programs are delivered in one package that is downloaded from a third-party site that hosts shareware and freeware.

After a rather deceptive infiltration, Cleanserp changes the settings of all the installed browsers without asking for direct permission, although users can instantly see the changes to their homepage, new tab URL, as well as the search engine. Users can then notice further compromise, as the top search results are presented as sponsored links – these lead to affiliated sites.

Additionally, might occasionally redirect to suspicious or even dangerous websites, where other, potentially unwanted programs might be advertised. The unwanted browser activity is also accompanied by spying on user browsing data – this helps developers to distribute targeted ads in exchange for a higher profit. Finally, the infected users claimed that they struggled with Cleanserp removal – a feature that is more prevalent in malware.  According to the latest reports, the deceptive extension hides under “CleanSerp” or “QueryRouter” names.

While the browsing tool has been available on the Web already for a while, it became especially active in October 2017. Interestingly, French users[1] report the highest number of complaints about having elimination troubles. It seems that simply removing the related extension and the very search tool does not help.

Take a look at the below Cleanserp removal guidelines to find the solution. According to users' reports, automatic elimination is an efficient way to get rid of the infection.

Untabs plug-in and the search tool of them belong to the potentially unwanted programs (PUP)[2] category. The latter tends to direct infected browsers to and set it as the default search engine. According to the VirusTotal analysis[3], the website of the hijacker is not malicious. On the other hand, note that it has a very poor community rating. Furthermore, the main page does not contain HTTPS protocol,[4] the indicator of a reliable and safe site. browser is a PUP that might alter browser settings and hijack the startup of Firefox and Chrome web browsers.

The described browser hijacker might enter the target system silently in the software bundle, hijack web browsers’ settings, alter search results, display intrusive advertisements, and collect information about users.

So-called Cleanserp virus is not a malicious cyber threat; however, it might increase your chances to run into websites run by cyber criminals.[5] It might happen if you click on misleading online ad or link included in search results. However, the main issue appears when you attempt to remove Cleanserp and set the preferred search engine as the default one. 

The design of resembles Google. It has quick access to Gmail and G+, as well as allows carrying out web, image and video searches. In fact, its design resembles another infamous browser hijacker – virus[6].

If the site or its plug-in bothers in Chrome or Firefox, scan device with Reimage Reimage Cleaner Intego or Malwarebytes and let the anti-malware program to delete the infection for you.

Key characteristics of Cleanserp hijacker

Ironically, this PUP is promoted as a tool that respects user’s privacy. The Terms of Use indicates user’s responsibilities only. Meanwhile, developers’ obligations are not defined. In the Privacy Policy of Cleanserp, it is noted that search engine uses cookies to collect and store particular information about users:

  1. Your IP address;
  2. Search queries;
  3. Browsing history;
  4. Similar browsing-related details.

Besides, it can also collect and store some of your personal information if you decide to contact developers via email or reveal your name in any other way, for example, searching for your name and surname using this search tool. What is more, the suspicious search utility might also deliver third-party ads.

Cleanserp hijackerIn the Privacy Policy, Cleanserp authors warn users that they, along with the affiliates, place cookies on users' browsers. While the behavior is normal, it is also stated that some of the features will not work without them.

The Privacy Policy also states that third-party cookies[7] might be installed on your browser. Thus, unknown advertising networks or third-parties might spy on your online activities and display customimized advertisements.

Finally, keep in mind that the document tells that aggregated information is used for improving service. However, it actually means that this browser extension will deliver targeted ads. They might come in the form of pop-ups, banners or in-text ads. 

One of the most annoying features of this PUP is CleanSerp redirect. This browser infection can mislead people to sponsored websites and decrease users' browser's performance. As a result, you may be forced to browse through irrelevant websites and end up on potentially dangerous websites. Indeed, some of the ads or links might lead to misleading websites where you can be tricked into installing bogus software, revealing personal details or get infected with malware.

Thus, do not delay Cleanserp removal. Decrease the chance of possible threats and regain control over your browser. This hijacker mostly affects French computer users, so if you are one of them, we suggest looking for information on[8].

Ways to prevent potentially unwanted programs from entering your machine

Just like many other PUPs, the one we discuss today also spreads in the software bundles as an optional component. If users agree to install freeware or shareware under “Quick” or “Recommended” settings, they give indirect permission to all optional downloads to enter the system without even knowing it.

Cleanserp installed via software bundles

It happens because such setups do not openly disclose about third-party software. In order to avoid Cleanserp hijack and similar browser hijackers, users need to choose “Advanced” or “Custom” installation option. However, only clicking “Next” button as fast as possible won’t prevent your PC from browser hijacking.

It’s crucial to monitor the process and uncheck all pre-selected entries. If you overlook this important step, you might be surprised how many undesired apps might be installed on your device.

Eliminate from Chrome browser

In order to avoid this problem, you can opt for automatic Cleanserp removal option and run a full system scan with anti-malware/anti-spyware program.

CleanserpCleanserp sets its search engine as default one, and users struggled to return it back to normal.

We do not recommend following instructions provided on hijacker's search site because they are very unclear and, to say the least, confusing.

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
