PDFSearchz – a potentially unwanted application that hijacks your searches

Once installed, it would perform several browser changes, including modification to the homepage and new tab address (it is set to After the hijack, the PUP would redirect all searches to Yahoo, insert intrusive ads, and track user activity for marketing purposes.

PDFSearchz hijacker belongs to a broader group of PUPs that are most commonly rebranded and distributed as a new product. Previously-released apps include HDSportSearchs, MovieSearches, FunSearchToday, and many others. These apps are almost virtually identical, as the only difference is the icon used to promote them. Otherwise, the functionality remains the same – to hijack user browsers and deliver sponsored content, earning profits in the process.

And, since PDFSearchz most commonly gains access to users' computers in deceptive methods such as software bundling, the developers include several attributes to make people keep it installed for as long as possible. For that, the hijacker inserts seemingly useful features, such as a cryptocurrency converter or a calculator. However, don't let these features deceive you – there is very little use of them.

Since the so-called PDFSearchz virus engages in the browser modifications, users always find the as their homepage, new tab, and search engine address. When used, users will quickly notice that Google is redirecting to Yahoo, and that search results look nothing like they are used to.

Despite Yahoo being a legitimate and trusted search engine, the browser hijacker inserts sponsored links to unknown websites. Since they are placed at the top of search results, users are likely to click on them, generating profits for the developers though the pay-per-click[1] scheme. The only way to stop this behavior is to remove PDFSearchz from their web browsers or computers.

Another deceptive trait of a browser hijacker is that it is set to spy on users' online behavior. With the help of cookies, web beacons, and similar technologies, the developers of the app are capable of spying on users' searches, visited websites, clicked links, IP address, ISP provider, and much more. This behavior is described on's Privacy Policy page:[2]

Non-Personal Information may be automatically transmitted by the user's device. When using our Service, we assign your device with a log file, a cookie (session or persistent), web beacons or other related technologies, to collect Non-Personal Information with respect to your activity in connection with our Service.

While in most cases the PDFSearchz hijack is related to an extension that is likely to be clipped to the web browser, it might be difficult to eliminate, as previous members of the hijacker family used to apply “Managed by your organization” feature. This would prevent users from uninstalling the extension easily.

However, there are ways to bypass this when attempting PDFSearchz removal. In most cases, users should be able to delete the extension in a regular way. If not successful, you should try to clean the web browser as instructed in the guidelines below. It is also recommended to scan the machine with anti-malware tools and then attempt repair Windows damage with Reimage Reimage Cleaner Intego.

PUPs spread through software bundles – use correct installation settings of freeware

Most users are aware that malicious programs exist somewhere on the internet and by now know that downloading suspicious executables can be dangerous. However, potentially unwanted applications are being spread around regularly, and what users describe as “stealthy installation” is not that mysterious after all. This is because PUP authors and distributors employ software bundle packages to install apps behind less cautions users' backs. 

While bundles can be encountered on most third-party sites,[3] freeware apps are where the issue lies. The main goal of distributing “free” software is showing visitors ads or making them install applications that never intended in the first place (there is no such a thing as completely free software unless it is open source). To slip in PUPs, developers employ pre-ticked boxes, fine print text, misleading button placements, and other tricks that would make users not notice the optional components within the installer.

PDFSearchz distributionPDFSearchz can be found on various websites as well as software bundles downloaded from third-parties

Therefore, it is vital to be vigilant when installing new apps on the system. You should never rush through steps, read the installation instructions carefully, and, most importantly, always choose the Advanced or Custom settings rather than Recommended ones. If the latter is chosen, you automatically agree to install apps you know nothing about. Also, a robust security application can warn you about PUPs, so you should keep an updated anti-malware on your system at all times.

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
