Remove PDF Opener [Explained]

What is PDF Opener

PDF Opener is a browser hijacker promoting a fake search engine pdfsrch.com. It’s advertised as a useful extension that will help convert files to PDF. However, it’s very unlikely that you installed the extension yourself because the chances of you coming across this particular one are pretty slim. It’s much more likely that you installed free software that had this pest attached to it. This is referred to as software bundling, and is a common installation method used by unwanted program developers. We will explain this and how to avoid these unwanted installations further on in this report.

In the meantime, we should quickly explain what exactly this hijacker does. It will change your browser’s settings and set its promoted site as your homepage and new tabs, as well as change your default search engine. These changes will be performed without your permission and will be irreversible while the hijacker remains installed. The hijacker aims to redirect you to sponsored sites in order to generate traffic and revenue. Because the sites you could be redirected to will not be checked, you could easily be exposed to malware and all kinds of scams. Thus, we strongly recommend you delete PDF Opener.

How does PDF Opener install?

You may be able to find the extension available on some sites but with the amount of similar extensions available, it’s very unlikely that you would stumble upon this one in particular. It’s much more likely that PDF Opener was attached to some free program you installed. This is called software bundling. Essentially, PDF Opener was attached to a free program as an extra offer, and when you installed the program, PDF Opener installed alongside.

These offers are optional but are preselected to install alongside the program. They’re also hidden which is why users install these offers so often. To make them visible, you need to opt for Advanced (Custom) settings during freeware installation. Unlike Default settings, Advanced will make all extra offers visible, and you will be able to deselect all of them. Uncheck the boxes of those offers and you can then continue installing the program.

Keep in mind that most free programs will come with these offers attached. And unless you want to fill your computer with junk programs, you should always pay attention to what program you install and how you do it. Deselecting a few boxes takes seconds, compared to uninstalling adware and hijackers.

Is PDF Opener dangerous?

The extension will attach itself to popular browsers like Google Chrome and Mozilla Firefox, and change their settings. It will set its promoted site as your new homepage/new tabs, and change your default search engine. These changes are very obvious and you will immediately notice. Do not waste your time trying to undo these changes while the hijacker is still installed because it will just keep changing everything back.

The extension is promoted as a file converter but it won’t really do anything. It’s main intention is to redirect you to sponsored sites to generate traffic and revenue. If you perform a search via your browser address bar, you will be redirected to pdfsrch.com and then to Yahoo. Yahoo is a perfectly legitimate search engine, but you do not need to put up with the hijacker forcing you to use it. You also do not need to go through a third-party website to access Yahoo when you can go there directly.

The hijacker will also collect information about your browsing activities. It will track what sites you visit, what you search for, what content you engage with, your IP address, etc. This information can later be shared with unfamiliar third-parties.

Overall, PDF Opener is a useless extension that is classified as browser hijacker. It makes unwanted browser changes, tries to potentially redirect you, and collects information about your activities.
