What is TopPDFSearch browser hijacker?

TopPDFSearch browser hijacker – a PUP that fills search results with deceptive ads

TopPDFSearch browser hijackerThe browser hijacker alters browser settings to promote a search engine of its choice

TopPDFSearch is a browser hijacker, although it might seem like a useful tool at first sight. It offers an on-page PDF and currency converters, cryptocurrency overviews, and a calculator. But if you type in a query into the search field, a new page opens with results from Searchlee will be shown. However, the search provider might depend on your geolocation.[1]

The search results contain tons of various ads. It's not safe to click on any of them as they're generated by the article's culprit. Potentially unwanted program[2] distributors don't care about the privacy and safety of their users, so they advertise whoever pays the most.

That's why TopPDFSearch ads might lead to dangerous sites with malware, tech support scams, push notification viruses, etc. Please refrain from clicking on them or trying to close them as the “Close” or “X” buttons might disfunction and open an affiliated portal anyways.

Furthermore, this type of software modifies every browser installed on your device by changing their default search engine, new tab, and homepage preferences. In this particular case, all settings are altered without the user's direct consent to promote portal.toppdfsearch.com.

Moreover, browser hijackers have data-tracking capabilities. Such PUPs usually collect non-identifiable information (IP addresses, geolocations, search inquiries, URLs of visited sites, etc.). Still, in some cases, they could gather personal details, such as emails, names, and so on.

Based on the aggregated information (aka your browsing habits), the PUP operators customize advertisements specifically for you, so they might seem irresistible. Sometimes, the information is shared with or sold to third parties to increase revenue.

Therefore we strongly recommend our readers remove TopPDFSearch browser hijacker, and the sooner, the better. This article contains comprehensive instructions to help you get rid of this intruder, whether it's installed as an app or a browser extension, and repair virus damage.

Potentially unwanted programs, including the article's culprit, usually end up on devices without their owners knowing about it. That happens when you download a software bundle from third-party vendors. They use this technique to increase their revenue.

Additional applications aren't disclosed, and as soon as you pick the Standard, Quick, or Recommended installation mode, all of them are automatically installed. Even some legitimate software vendors and developers are using this deceptive technique. Therefore you need to be careful when installing any new apps.

One way to evade TopPDFSearch and PUPs like is to choose the Custom or Advanced installation mode and go through the whole process step-by-step, deselecting all unreliable, suspicious, unwanted apps from installing on your device. Another way is to have a proper anti-malware tool like the Malwarebytes that will block you from installing such software.

Such apps will protect your device from various malware that's lurking on the internet and waiting for users with insufficient cybersecurity levels.

How to prevent from getting browser hijacker

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.
