QuickPDFConverterSearch is a potentially unwanted application that shows you ads whether you like them or not

QuickPDFConverterSearch is a browser-hijacking application that might show up on your browser without warning. This mostly happens when users get tricked by a fake advertisement (for example, a fake Flash Player update),^[1] or when they download software installers that bundle^[2] applications.

Once on the device, the hijacker would alter the settings of Google Chrome, Mozilla Firefox, MS Edge, or another web browser. The most significant change that users spot immediately is the homepage being altered to portal.quickpdfconvertersearch.com, which changes it visually a lot. However, the function of these newly established preferences is what matters the most.

As soon as the new search box is applied, users are forced to use an alternative search provider, such as searchlee.com, nearbyme.io, yahoo.com, or bing.com (depending on your location and other preferences), which shows alternative search results filled with ads and sponsored links. Besides, QuickPDFConverterSearch would also track user data in the background, which could result in significant privacy risks for those affected.

QuickPDFConverterSearch overview

QuickPDFConverterSearch comes from an established browser hijacker family that has been spreading around for several years now, with hundreds of versions released – BestMapSearch, BestSportSearch, or FreeSearchStreams are just a few examples we've already covered before.

If looking at the names used, one could quickly make a conclusion here: they are meant to imply some kind of functionality, be it PDF conversion, blocking ads, or finding music fast. However, this is not the case, and these apps have little to do with these functions.

All they can offer is a basic search feature that redirects results to an alternative provider and inserts ads at the top while doing so. Also, all of the browser hijacker versions are mere copies of one another and offer no variety in what they are capable of doing.

Distribution and prevention

Whenever a potentially unwanted browser extension is installed on the system unintentionally, users are surprised to see their homepage and new tab settings being different from the usual. This usually happens when people install freeware from third-party sources and accidentally agree to implement optional components.

Users are often busy with their daily tasks, so it is not surprising that they want to be done with the installation process of new software – they skip through steps and click the “Next” button until it is all over. This is one of the biggest mistakes one can make when dealing with free software downloaded from the internet, and third-party sources are well aware of that.

QuickPDFConverterSearch gathers various information from the affected users

Software binding is essentially legitimate and is used to offer users trying optional products. However, freeware distributors often intentionally use misleading techniques to make people install other apps. In order to avoid being a victim of this, you should follow these tips from security researchers:^[3]

• When possible, download software from official sources only;
• Before downloading an app you know nothing about, read reviews online about it;
• During the installation, always pick Advanced/Custom settings instead of Recommended/Quick ones;
• Remove all ticks from pre-ticked checkboxes;
• Read the fine print and watch out for misplaced “Agree to offer” buttons;
• Install powerful security software, such as SpyHunter 5Combo Cleaner or Malwarebytes, to protect yourself from PUPs and malware.

QuickPDFConverterSearch elimination

In order to regain control of your web browsing, you should get rid of the browser hijacker. In order to do so, you should find and remove the extension that caused the changes. Otherwise, you will be forced to use the alternative search provider and see alternative search results with ads.

Usually, you can eliminate the hijacker by clicking the “Extensions” button next to the settings menu. If that is not possible for some reason, you can proceed with the following instructions instead:

Google Chrome

• Open Google Chrome, click on the Menu (three vertical dots at the top-right corner) and select More tools > Extensions.
• In the newly opened window, you will see all the installed extensions. Uninstall all the suspicious plugins that might be related to the unwanted program by clicking Remove.

Mozilla Firefox

• Open Mozilla Firefox browser and click on the Menu (three horizontal lines at the top-right of the window).
• Select Add-ons.
• In here, select unwanted plugin and click Remove.

MS Edge

• Open Edge and click select Settings > Extensions.
• Delete unwanted extensions by clicking Remove.

Safari

• Click Safari > Preferences…
• In the new window, pick Extensions.
• Select the unwanted extension and select Uninstall.

In order to make the browser-hijacking scheme as effective as possible, its authors often gather user information, such as visited websites, clicked links, search queries, browser and device technical data, IP address, ISP, and more. All this automatically-collected information helps third parties with advertising, which brings more money for all involved parties.
