How to remove 1 Click PDF from Mac?

What is 1 Click PDF?

1 Click PDF (also known as 1ClickPDF) is promoted as a file conversion app capable of converting virtually any file format to PDF. It is promoted as a useful and legitimate tool, however, 1 Click PDF is categorized as a potentially unwanted (adware-type) application (PUA) and adware. It changes browser settings, feeds users with ads, and gathers information. Do not trust or use the 1 Click PDF converter.

1 Click PDF adware

If installed on Google Chrome, this app changes browser settings - specifically, the default search engine. It might also affect other browsers in this way. Furthermore, 1 Click PDF uploads all files that users attempt to convert to a remote server. It is stated that these uploaded files are deleted after one hour following upload, however, it is also mentioned that the developers might use this app to collect system information and share it with partners (various third parties). Therefore, these 'partners' might also share uploaded files. PUAs often gather information such as IP addresses, geolocations, URLs of visited websites, entered search queries, and other similar data. The information might be shared with cyber criminals who misuse it to generate revenue. Furthermore, adware-type apps feed users with various ads such as pop-up, banners, coupons, surveys, and so on. These ads conceal underlying content of visited websites, and if clicked, can execute scripts designed to download and install other PUAs. Some of these apps could also be malicious. When used, 1 Click PDF app regularly promotes dubious applications. For example, if installed on the Safari browser, it opens the bestformac[.]net website, which promotes the MacKeeper potentially unwanted application. This website also asks permission to show notifications. Typically, if websites of this type are able to show them, they start to deliver various ads, irrelevant notifications, and other unwanted content. In summary, we advise against having adware-type apps installed and recommend that you uninstall 1 Click PDF immediately.

The internet is full of PUAs of this type. Some examples of other adware-type apps are ApplicationWork, TopicLookup, and ChangeToPDF. Typically, developers present them as 'useful' tools that supposedly provide various features, however, PUAs are generally designed to generate revenue for their developers. Furthermore, they deliver no real value for regular 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, most people download and install PUAs unintentionally or accidentally - often by clicking various intrusive ads that should not be trusted. In other cases, people download and install unwanted apps together with  other programs. This happens when developers bundle (include) PUAs into software set-ups and do not properly disclose information regarding their inclusion. They hide information regarding PUAs in "Custom", "Advanced" and other similar settings options of the download and installation set-ups. Thus, leaving these settings unchanged usually causes unwanted downloads and installations.

How to avoid installation of potentially unwanted applications?

Use official and trustworthy websites to download software. Third party downloaders, dubious (unofficial) websites, Peer-to-Peer networks and other similar channels should not be trusted. Download and install software properly. Do not skip any setup steps without checking "Custom", "Advanced" and other similar settings. Also deselect offers to install potentially unwanted apps. Avoid clicking intrusive advertisements, especially if they are displayed on pages relating to gambling, adult dating, pornography, and so on. If clicked, they either open potentially malicious websites or download/install unwanted apps. If you continually encounter unwanted ads or redirects, check for any unwanted, dubious extensions, plug-ins, and add-ons installed on the browser and remove them immediately. Also apply this to unwanted programs installed on the operating system. 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.
