ProPDFConverterSearch Browser Hijacker – Detailed Overview
ProPDFConverterSearch is one of those search engines that hijack browsers to obtain searches and redirect browsing to other bogus engines. Similar sites are TopPDFSearch, PDFSearchly, and PDFConverterSearchPro. The presence of this site on your browser relates to the unnoticed installation of a potentially unwanted program – a browser hijacker.
The design of this search engine is simple and intuitive as the hijacker aims to stay active on the system for as long as possible. However, browser hijackers are apps that lower online security by activating tracking technologies like cookies, collecting specific data, redirecting affected browsers to other bogus sites, and displaying adverts.
The data that may be harvested by the use of cookies, web beacons, scripts, etc. includes:
- Visited URLs and websites;
- Type of used browser;
- Search queries;
- Search queries on the visited web pages;
- Operating system type;
- The domain name of current Internet service provider (ISP);
- Internet protocol (IP) address;
- Geographic location;
- Browser’s home page;
- Diagnostic information which describes how their Services are operating on the system.
Harvested data helps ProPDFConverterSearch’s owners to set shady advertising campaigns that target your interests and demographics. Fraudsters hope that a more precise targeting will make you more prone to visit sponsored web pages. Every click on an ad generated by their tool generates revenue.
Note that some of the ads may link to poorly secured or hacked websites. So, please be careful when interacting with bogus ads and consider a thorough check of the security of your PC.
The usage of the searching services offered by this site should also be avoided. During our research, we identified that the hijacker redirects all searches to Searchlee hijacker. This issue enables both ProPDFConverterSearch and Searchlee hijacker to record data and provide it to unknown actors.
For the sake of your PC and online security, it’s best to consider the immediate removal of ProPDFConverterSearch from the affected browser and system.
