How to remove PDFConverterWeb browser hijacker and its redirects?
Written by Tomas Meskauskas on
What is PDFConverterWeb?
PDFConverterWeb is a piece of browser-hijacking software promoting the pdfconverterweb.com fraudulent search engine. Additionally, due to the questionable methods used to spread browser hijackers, they are also classified as PUAs (Potentially Unwanted Applications).
PDFConverterWeb browser hijacker overview
Browser hijackers (e.g., PDFConverterWeb) reassign browsers' homepage, default search engine, and new tab/window URLs - to fake web searcher addresses (e.g., pdfconverterweb.com). Hence, new browser tabs/windows opened and web searches performed via the URL bar - redirect to the promoted address.
Fraudulent search engines usually cannot provide search results, so they redirect to legitimate ones. This also applies to pdfconverterweb.com; it redirects to Yahoo or the nearbyme.io fake web searcher. While nearbyme.io can generate search results, they are inaccurate and may endorse untrustworthy/malicious sites.
Furthermore, browser hijackers can undo the 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 hijacking it.
What is more, most browser hijackers can track data. The collected information (e.g., browsing/ search engine histories, personally identifiable details, etc.) is then shared with and/or sold to third-parties. In summary, this software can cause severe privacy issues, financial losses, and even identity theft.

Browser hijackers in general
Perfect-Converter, SocialCouponSearch, and DirectConverterz are a few examples of browser-hijacking software. It appears legitimate and offers "useful" functionalities, which usually do not work. This is true of nearly all PUAs. Unwanted apps are designed to hijack browsers, force-open dubious/malicious sites, run intrusive advertisement campaigns (adware), and gather sensitive data.
How did PDFConverterWeb install on my computer?
PUAs are distributed using the "bundling" technique - pre-packing ordinary programs with unwanted/malicious supplements. Rushed downloads/installation processes increase the risk of inadvertently allowing bundled content into the system.
Intrusive advertisements proliferate PUAs as well. Once clicked on, the ads can execute scripts to make downloads/installations without user permission. Some PUAs also have "official" promotional/download pages.
How to avoid installation of potentially unwanted applications?
It is recommended to research software and only download it from official/verified channels. Untrustworthy download sources, e.g., unofficial and freeware websites, Peer-to-Peer sharing networks, etc. - often offer bundled content.
When downloading/installing, it is advised to read terms, study possible options, use the "Custom/Advanced" settings, and opt-out from all supplements. Intrusive adverts appear legitimate, yet they redirect to various questionable sites (e.g., gambling, pornography, adult-dating, etc.).
In case of encounters with advertisements and/or redirects of this type, the system must be checked and all suspect applications and browser extensions/plug-ins detected - removed from it without delay. If your computer is already infected with PDFConverterWeb, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
