Pdf2DocPro – a suspicious browser extension that infects users machines without permission

Pdf2DocPro is a questionable application and a browser hijacker[1] which claims that it can convert all PDF files into other formats in just a few seconds directly from the browser. However, its dubious redirection tendencies, information tracking, and over-the-top advertisement make users question its functionally.
| Name | Pdf2DocPro |
|---|---|
| Promoted as | Browser extension |
| Author | PERION NETWORK LTD |
| Official website | hxxp://www.pdf2docpro.com/ |
| Distribution | Bundling, official website |
| Symtoms | Modified browser settings, compromised browsing experience, invasive ads and redirects, etc. |
| Dangers | Possible information leakage and malware infections |
| Elimination | You can download FortectIntego and perform full system scan |
Pdf2DocPro typically infiltrates victims’ computers with other programs they download off the internet. Thus, users might not be aware of a browser hijacker presence at first. Nevertheless, as soon as Google Chrome, Internet Explorer, Mozilla Firefox or other browser is put to use, users can immediately notice changes made:
- the homepage and search engine are altered to chrome-extension://ndgiipgjbobbpfaoceclhnckcagimhcn/html/newTab.html;
- quick action buttons added to the main page;
- search results promote additional sponsored content;
- some websites redirect to questionable realms
- ads and pop-ups cover up the background of legitimate sites, etc.
The easiest way to eliminate these unwanted changes is to install a robust security tool like FortectIntego, perform a full system scan and remove Pdf2DocPro extension for good. Alternatively, you can use our manual instructions below this article.
Some users might find the converting function useful. However, do not get deceived by this functionality, as the only intention applications’ authors have is to extort money by displaying affiliated content and controlling users browsing habits. If you need to convert a file, find a legitimate source to do so without compromising your browser.
Links to third-party websites Pdf2DocPro provides might not always be safe. Therefore, the redirecting tendencies are by far the most dangerous. Users might end up on fake software, phishing or malware-infested realms. Malicious JavaScrips[2] might install malware directly into victims’ PCs without them noticing. Once that happens, the damage to computer files or information leakage is inevitable.
Just as many browser hijackers, Pdf2DocPro is capable of spying on its victims by collecting non-personally identifiable information. In addition to non-PII, the questionable app might collect personal data provided by you (like credit card details, name, address, social security number, etc.).
Besides, third-parties might also obtain your information. The Pdf2DocPro authors mention the following:
<…> the Company provides such third parties with a large number of tools to enable them to create interesting and unique apps, buttons, and gadgets using the Company’s platform. Some of these tools may give these third parties the ability to access, collect, store, and/or share your information – both your PII and non-personally identifiable information. In order to clarify, we do not review, approve, monitor, endorse, warrant, or make any representations with respect to such Third Party Content and Services and your access to any Third Party Content and Services is at your own risk.
Security experts[3] warn that Pdf2DocPro removal should not be delayed as it can lead to identity theft or stolen money from your bank account. Additionally, it is crucial to eliminate the virus before it installs more PUPs or infects your machine with malware.

The ways unwanted applications spread
Although the application can be downloaded from Google Chrome store, its primary distribution method is bundling. It is a deceptive marketing campaign used by free software developers. Therefore, if you want to avoid suspicious applications, we advise you to be attentive while installing free software and browsing the internet.
It is crucial to pick the correct source before downloading an unknown program, as third-party domains might be infested with numerous dangerous apps. Thus, always choose official websites for your new software and its updates.
While installing a new application, make sure you choose Advanced/Custom installation mode instead of Recommended/Quick one. Once prompted, untick any tick marks present by search engines, extensions, media players, toolbars, etc.
Delete Pdf2DocPro from your machine and stay safe
Pdf2DocPro removal can be performed in two ways: manual and automatic.
If you want to get rid of Pdf2DocPro virus quickly and without much effort, we strongly suggest picking automatic elimination method. All you have to do is download one of the proposed security programs and install it on your machine. Then, run a full system scan.
