How to remove the SearchPDFConverters browser hijacker?
Written by Tomas Meskauskas on
What is SearchPDFConverters?
SearchPDFConverters is a browser hijacker promoting the searchpdfconverters.com fake search engine. Software products within this classification are also considered to be PUAs (Potentially Unwanted Applications).
SearchPDFConverters browser hijacker in detail
SearchPDFConverters assigns searchpdfconverters.com as browsers' default search engine, new tab/window, and homepage URLs. Hence, every search query typed into the URL bar and new tab/window opened - redirect to searchpdfconverters.com.
Fraudulent search engines usually cannot provide search results, so they redirect to legitimate ones. This applies to searchpdfconverters.com as well; it redirects to the genuine Yahoo (search.yahoo.com) and fake searchlee.com search engines (possibly others). While searchlee.com can generate search results, they are inaccurate and may endorse unreliable and malicious content.
Browser hijackers can reset any changes users try to make to their browsers or restrict/deny access to the browser settings. Therefore, restoring a browser is impossible without removing the software affecting it.
Furthermore, browser hijackers usually monitor users' browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect sensitive information extracted from it (IP addresses, personally identifiable details, etc.). The gathered data is then monetized by being shared with and/or sold to third-parties.
In summary, the presence of data-tracking software on devices can lead to serious privacy issues, financial losses, and even identity theft.

Browser hijackers in general
GreatSearchPDF, TigerVideoSearches, SearchStreamz - are a few examples of browser hijackers. They appear harmless and use fake features to lure users into download/installation. This applies to nearly all PUAs. Unwanted apps are designed to hijack browsers, force-open dubious/malicious sites, run intrusive advertisement campaigns (adware), and collect private data.
How did SearchPDFConverters install on my computer?
PUAs can have "official" download webpages. Intrusive advertisements are also used to spread these applications. Once clicked on, the ads can execute scripts to make stealthy downloads/installations. PUAs are mainly distributed by using the "bundling" technique - packing regular software with unwanted/malicious additions. Rushed download/installation processes increase the risk of allowing bundled content into the device.
How to avoid installation of potentially unwanted applications?
It is advised to research software and download only from official/verified sources. Untrustworthy download channels, e.g., unofficial and freeware sites, Peer-to-Peer sharing networks, and other third-party downloaders - offer bundled content.
When downloading/installing, it is recommended to read terms, study available options, use the "Custom/Advanced" settings to opt-out from additional apps, tools, etc. Intrusive adverts appear legitimate; however, they redirect to questionable websites (e.g., gambling, pornography, adult-dating, and so on).
In case of encounters with such ads and/or redirects, the device must be inspected and all suspicious applications and browser extensions/plug-ins detected - immediately removed from it. If your computer is already infected with SearchPDFConverters, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
