Compresspdfsearch.com – the search engine that might hide sponsored links in the results page

The picture of Compresspdfsearch.com

Compresspdfsearch.com is a suspicious search engine created by Hopebest Inc. It’s not the first program created by this company. However, all search tools are defined as browser hijackers and potentially unwanted programs (PUPs).

The main reasons why security experts called this tool as PUP are:

  • questionable distribution method that is known as “bundling;”
  • alteration of Windows Registry, shortcuts and browsers’ settings;
  • replacement of default homepage and search engine to Compresspdfsearch.com;
  • delivery of ads and other sponsored content;
  • data tracking.

This search tool has an additional feature that allows compressing PDF files from the main page. However, the program does not complete it’s primary function properly. According to the research results, this search tool might alter search results and replace organic links with paid links.[1]

The main purpose of the Compresspdfsearch.com virus is generating advertising-based revenue for the developers. Thus, when this program is installed on Chrome, Firefox, IE or another browser, it starts providing numerous online ads, pop-ups, banners or even redirecting to promotional websites.

The biggest problems are that sponsored links might be hidden in the search results page and lead to potentially dangerous websites. Compresspdfsearch.com redirect issues are concerning. Thus, in order to avoid meeting with cyber criminals and malware, you should stay away from ads and do not use this tool in general.

However, Compresspdfsearch.com removal might be complicated due to hijacker’s ability to make modifications to the system. It is designed to protect itself and prevent users from setting their preferred search provider. Thus, in order to get rid of this program, users are advised to use Reimage or another anti-malware.

Manual elimination is also possible. However, our colleagues from SenzaVirus[2] noticed that users often make mistakes and leave some of the hijacker-related components installed. Usually, they forget to reset hijacked web browsers. As a result, cookies and other publisher’s or affiliate’s tracking technologies continue spying on user’s activities online.

Indeed, the Privacy Policy states that the search engine collects some information about users, including IP address, visited websites, search history and keywords, and similar information. However, developers are collaborating with advertising companies and networks. Thus, unknown third-parties might be collecting various information about you as well.

Thus, you need to remove Compresspdfsearch.com to protect your privacy[3] and avoid the attack of aggressive and annoying commercial content. The instructions below will show you how to delete tracking cookies and other virus-related components manually.

Bundling helps to install the hijacker to computers silently

Authors of the hijacker rely on the popular distribution method of PUPs – bundling. It’s software marketing technique that allows spreading the hijacker with the help of various programs that you can download from the Internet.

The PUP is added as an optional component in the software package. It is hidden under Quick or Recommended settings that do not openly disclose about the installation of the third-party software. Thus, when users install new programs under these settings, they might encounter Compresspdfsearch.com hijack.

To avoid infiltration of this search tool and many other undesired applications, you should get used to install software using Advanced/Custom setup and pay attention to each of the installation steps. These settings might show the list of additional third-party programs. Typically they are pre-selected; thus, you need to untick them in order to stop their installation.

Remove Compresspdfsearch.com virus from the computer and web browsers
