HDPDFConverterSearch browser hijacker Removal Guide

What is HDPDFConverterSearch browser hijacker?

HDPDFConverterSearch is a bogus plugin that can cause erratic browser activity


HDPDFConverterSearch is a browser hijacker that can change the main settings of the browser. It changes the homepage to portal.hdpdfconvertersearch.com and redirects search queries through feed.hdpdfconvertersearch.com to one of these search engines – Bing, Yahoo, Searchlee, or Nearbyme. While Bing and Yahoo are well-known and trusted engines, the other two are not. They do not provide special algorithms or anything else useful.

It can also cause an increased amount of commercial content, like pop-ups, banners, and redirects. Fraudsters can generate revenue with pay-per-click advertising.[1] The plugin is only beneficial to its creators. It belongs to a family of hijackers. They all have the same basic functions – a PDF file converter, calculator, currency converter, and the ability to add your favorite pages. The truth is that these functions are accessible with a click of a button almost on every browser.

FURTHER STEPS Use FortectIntego to fix any remaining damage and optimize the machine

Distribution methods

Browser hijackers are usually spread through bogus “Download” pages and deceptive ads. Visiting shady sites on the internet can also cause issues. For example, illegal streaming platforms are rarely regulated, so they are full of deceptive ads, sneaky redirects, fake “Download” and “Play” buttons.

Another important thing to know is that freeware distribution sites are not trustworthy. Often they use software bundling to monetize their activity and they do not disclose that on the site in the hopes that most people will not notice. Unfortunately, that is what happens most of the time as people find the installation process boring and skip through the steps.

It is best to use official web stores whenever you want to install browser extensions. Apps that get listed there go through an extensive review process. However, you should still do your research, and read the reviews, look at the ratings, and the number of users the plugins have. Choose those applications that have plenty of positive feedback and thousands of users. It is also recommended to read the descriptions fully as fraudsters often make grammar or spelling mistakes.

Cookies track your browsing history

Almost every website you visit uses cookies[2] to gather information about your websites, links you click on, and purchases you make. This data can be later sold to advertising networks that use it to target you with advertisements even more. Also, if you visit many websites that do not have strong security in place, cookies can be hacked and used for malicious purposes.

If you had your browser hijacked, you most likely visited some shady sites, which means it is unknown who has access to your cookies. It can be sold to advertising networks or other third parties. There is an automatic solution to this FortectIntego, which can also fix corrupted files, system errors and improve your device's performance which is very helpful after virus infections.

Stop uninvited guests from performing unwanted changes

Potentially unwanted applications[3] are mostly spread on freeware distribution sites with the method of software bundling.[4] It is always best to use official web stores because the risk of installing a bogus program is minimal. We know paying for software can get costly, so if you will continue to download free software there are precautionary steps you can take to prevent PUP invasion:

  • Always choose the “Custom” or “Advanced” installation methods
  • Read the Terms of Use and Privacy Policy
  • Untick the boxes next to files you do not need
  • Have professional security software installed to perform system scans regularly

Anti-malware tools can help detect such applications that perform tasks without your knowledge. They can also be used to eliminate suspicious programs with all the related files. We recommend using SpyHunter 5Combo Cleaner or Malwarebytes because the PUP can be difficult to identify – often they get disguised as handy tools that you would not even suspect.

How to prevent from getting browser hijacker

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
