Queryservice.net might deliver sponsored search results that lead to ad-filled sites

Queryservice.net is a search engine that is widely promoted in software bundles. Due to the stealthy distribution method and ability to take over the targeted web browser and change its settings without permission. Just as it is typical to a browser hijacker, it alters the search engine and the homepage address to a customized one. While these changes might seem insignificant, the web browser experience completely changes after this – not in a good way.
| Name | Queryservice.net |
| Type | Browser hijacker |
| Distribution | Software bundle packages, third-party websites |
| Symptoms | Homepage and new tab URL changes; redirects to a customized search provider; sponsored links at the top of search results |
| Removal | Uninstall PUPs by following our manual guide or employ antivirus program |
| System fix | After the elimination of adware or malware, we highly recommend running a scan with FortectIntego repair software |
After the hijack occurs, users find a new search tool as soon as they launch their web browsers. Nevertheless, it might seem legitimate; you should not trust it. The program uses its search algorithm, and this helps to alter search results and include sponsored links.
The Terms of Use of the app reveals that users might find advertisements on the results page[1] because they are important to keep their service free of charge. Indeed, there’s nothing bad or illegal with this practice until partners and affiliates are reliable. However, the research showed up quite the opposite results.
The problem with these paid links is that they might redirect to questionable or even potentially dangerous websites. Therefore, you can accidentally end up on a phishing website or get infected with some cyber infection. Due to these redirect tendencies, we highly recommend taking action as soon as you notice changes in your web browser.
Unfortunately, QueryService removal may not be simple. The hijacker usually installs browser helper objects, modifies Windows registry and shortcuts. All these alterations help PUP to protect itself from removal. Therefore, if you decide to reject the hijacker’s changes on Chrome, Firefox, Explorer, or another hijacked browser, your alterations will be denied.
To remove the hijacker entirely, you have to check the list of installed programs and browser extensions.[2] Elimination requires deleting all suspicious entries and resetting each of the web browsers. However, you can speed up this procedure with SpyHunterCombo Cleaner or another anti-malware by scanning the system with an updated tool. To clean your web browsers quicker, we recommend using FortectIntego.

Questionable data tracking capabilities
The Privacy Policy of the program tells that after the installation, it might gather particular information about the user. According to the document, the program does not purposefully collect personally identifiable information, such as your full name or contact information. However, the hijacker can collect non-personally identifiable details:
- IP address,
- type of browser and operating system,
- unique software ID,
- version and other details of the installed Software,
- information about installed partners’ products,
- keyword and error search queries.
The problem is that is information might be shared with partners. Nevertheless, the document claims that these data are not used for marketing purposes; computer users complain about noticing an increased amount of online ads once they started using this search tool.
Therefore, if you are concerned about your online privacy, you should not use any tool that shares information about you with unknown third parties. Thus, you should not agree to make this search engine your default one during freeware installation. But if you made a mistake and unintentionally installed it, you should get rid of the Queryservice.net virus immediately.
Software bundles help hijacker to travel
The browser hijacker spreads in software bundles as an optional download. The PUP mostly aims at American computer users, but it might also hijack devices in the UK, Spain, or France.[3] Thus, you should be aware of this popular distribution method.
Additional components are usually hidden under Quick/Standard settings, so when users install freeware or shareware under them, she or he might give indirect permission to all “optional downloads” get inside the system.
To avoid undesired apps, you should always opt for the Advanced/Custom setup and monitor each of the steps. Once you see the list of third-party programs, you should unmark them all.
Uninstall process of the unwanted apps
To remove Queryservice.net manually, you have to go to Add/Remove programs and look up the hijacker. Once you find it, double-click or right-click the item and choose the “Uninstall” option from the drop-down menu.
Once it’s done, we also suggest looking up suspicious browser extensions and resetting each web browser. The instructions below will show you how it’s done.
If you want to speed up the removal process, you should opt for the automatic elimination option. It requires installing security software, updating it, and running a full system scan. This would also ensure that there are no other potentially unwanted or even malicious programs running in the background of your PC.
