PDF Converter Hub is a browser hijacker which hijacks the Google Chrome as a useful extension

PDF Converter Hub virus

PDF Converter Hub is a browser hijacker which has mostly been targeting Google Chrome web browser. This extension is trying to convince gullible users into installing it by offering fast and easy PDF file viewing. All the user has to do is just install the PDF Converter Hub browser extension on Chrome. However, we do not recommend doing that as your web browser will be hijacked, e.g. you will let the virus change the default search engine to search.hpdfconverterhub.com and perform your searches via the new engine. Additionally, the PUP can modify the browser's homepage, new tab URL, cause dubious redirects, and even promote suspicious content by placing notifications all over the computer screen during browsing sessions.

Name PDF Converter Hub
Type Browser hijacker
Sub-type Potentially unwanted program
Danger level Low. Affects only web browsers
Browsers hijacked In this case, Chrome is the main target
OS infected Usually, Windows
Main symptom The default search engine is set to search.hpdfconverterhub.com
Distribution sources Other free programs, main page Pdfconverterhub.com, unprotected websites, infected hyperlinks and ads
Detection software For browser hijacker detection purposes, use FortectIntego

This tool is also known as PDF Converter Hub virus due to its ability to sneak into the system unnoticed and perform rogue processes. Once this potentially unwanted program modifies your web browser's search engine, you will need to use this suspicious engine until you get rid of the browser hijacker permanently. This means you will be receiving search results that are gathered from legitimate search engines such as Yahoo or Bing.[1]

Additionally, PDF Converter Hub might start placing suspicious-looking notifications on your computer screen too. Advertising is just another possibility to make income for the developers and program creators. However, note that the biggest income source comes from your browsing activity details such as most visited pages, saved bookmarks, and other similar content. The developers share this information with third-parties after collecting it.

This browser hijacker also has the capability of redirecting users to developer-sponsored pages. In some cases, you might be accidentally taken to a malware-laden website and catch a dangerous trojan or ransomware virus infection. In order to avoid this type of possibility, we recommend performing the PDF Converter Hub removal from your computer system and web browsers. For all suspicious software detection purposes, try installing and using FortectIntego.

Additionally, you can remove PDF Converter Hub virus from your Google Chrome web browser and Windows computer by using our step-by-step guide which is presented below this article. It is very important to eliminate the browser extension which is responsible for all suspicious activities. After successful elimination, you will see that your browser's search engine will be brought to normal and all changes that were performed by the browser hijacker are reversed.

Pdfconverterhub.com hijacks web browsers after the user opts for installing the rogue extension PDF Converter Hub. This dubious component can come unexpectedly together with other software or the user might accidentally install it by herself/himself while accessing suspicious hyperlinks on the Internet. Remember, that the key to computer safety is in your own hands. If you want to know how to use it properly, continue reading our below-written browser hijacker[2] avoiding measures.

Browser-hijacking apps can be met almost anywhere on the Internet 

According to computer security specialists from Virusai.lt news page,[3] browser hijackers are one of the most common potentially unwanted programs that bother numerous users (adware also, of course). Sadly, users' carelessness is the main cause of secret PUP installation. In order to avoid this unwanted installation possibility, you should:

  • always use only original downloaders and installers. If you choose secondary installing sources, rogue content might be able to sneak into the system easily. Avoid this by opting for the Custom or Advanced option that allows the user himself/herself to track all incoming objects.
  • keep a distance from rogue websites. Various third-party pages, especially, P2P networks[4] distribute suspicious-looking programs and their components. Dubious content comes injected into hyperlinks or advertising posts and installs into the system when the user clicks on them.
  • never skip downloading/installing steps. However, if you have chosen to perform the downloading or installing process of a particular program on your own, make sure that you do it very carefully to not let any suspicious content invade the system.
  • purchase strong antivirus protection. If you do not have an antivirus program on your computer already, you should browse the Internet and search for a recommended tool. Do not be afraid to invest in a truly reliable one as it will provide you with a wide range of features such as system scans, malware detection, computer optimization, etc.
