What is 1 Click PDF?

1 Click PDF (also known as 1ClickPDF) is promoted an app, a file converter that is capable of converting almost any file format to PDF. Simply said, it is promoted as a useful and legitimate tool. However, this app is categorized as a potentially unwanted (adware-type) application (PUA) and an adware. It changes browser's settings, feeds users with various ads and gathers various information. We do not recommend to trust (use) the 1 Click PDF converter.

1 Click PDF adware

It is known that this app, if installed on Google Chrome, changes browser's settings. To be more precise, it changes a default search engine. It is possible that it could be affecting other browsers this way too. Another problem with 1 Click PDF is that it uploads all files that user attempts to convert into a remote server. It is mentioned that all uploaded files are deleted one hour after the upload. However, it is also mentioned that its developers might be using this app to collect some system information and share it with partners (various third parties). It means that they might be sharing uploaded files as well. Besides, it is known that apps of this type often gather information such as IP addresses, geolocations, URLs of visited websites, entered search queries and other data of this kind. It is possible that it might be shared even with cyber criminals who will misuse it to generate revenue. Furthermore, adware-type apps feed their users with various ads. For example, pop-up ads, banners, coupons, surveys and so on. One problem with these ads is that they conceal contents of visited websites, another problem is that if clicked, they might execute scripts designed to download and install other PUAs. Some of these apps may be malicious. When used, 1 Click PDF app regularly promotes questionable applications. For example, if installed on the Safari browser, it opens bestformac[.]net website which is designed to promote the MacKeeper potentially unwanted application. Besides, this website also asks for a permission to show notifications. Typically, if websites of this type are allowed to show them, they start to deliver various ads, irrelevant notifications and other unwanted things. To sum up, we recommend to avoid having adware-type apps installed and to uninstall 1 Click PDF as soon as possible.

The Internet is full of PUAs of this type, some examples of other adware-type apps are ApplicationWork, TopicLookup and ChangeToPDF. Typically, their developers present them as useful tools that supposed to provide their users with some advantageous features and so on. Unfortunately, most of the times these apps are designed only to generate revenue for their developers. What is worse, they do not deliver any real value for their users and cause only problems.

How did 1 Click PDF install on my computer?

1 Click PDF is available for download on a website that its developers use to promote it. However, it is known that most people download and install PUAs unintentionally (accidentally). Once way to cause it is to click various intrusive ads that should not be trusted. In other cases people download and install unwanted apps together with some other programs. It happens when developers bundle (include) PUAs into various software's setups but do not disclose information about them being included properly. They hide PUAs (information about them) in "Custom", "Advanced" and other similar settings options of download and installation setups. Users who leave all these settings unchanged usually cause unwanted downloads/installations by themselves.

How to avoid installation of potentially unwanted applications?

Use official and trustworthy websites to download any software. Third party downloaders, questionable (unofficial) websites, Peer-to-Peer networks and other similar channels should not be trusted. Download and install software properly as well, do not skip any setup's steps without checking "Custom", "Advanced" and other similar settings. In other words, without deselecting offers to install potentially unwanted apps. Avoid clicking intrusive advertisements, especially if they are displayed on pages related to gambling, adult dating, pornography and so on. If clicked, they either open potentially malicious websites or download/install unwanted apps. If you constantly encounter unwanted ads/or redirects, see if there are any unwanted, dubious extensions, plug-ins or add-ons installed on a browser and remove them as soon as possible. These actions should be applied to unwanted programs installed on the operating system as well. If your computer is already infected with 1 Click PDF, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
