Remove 1 Click PDF virus from Mac

Get insights into the 1 Click PDF app’s adware activity and learn how to completely uninstall the affiliated extension from browsers and the Mac on the whole.

When it comes to the Mac application called 1ClickPDF, let’s get something straight – it actually provides the declared features, but with reservations. Its official facet might look like a lure as it claims to convert various types of content to PDF format. Technically, this functionality works directly via the address bar of the user’s current browser. All it takes is typing the word “PDF” in there and the appropriate dialog will instantly appear so that the user indicates what to convert, tweaks the properties of the process and triggers it. This sure sounds okay, but only at first sight. The pitfall number one is that the 1 Click PDF extension, when added to the browser, will hijack its search engine settings. Although the publisher of this software mentions on the product’s homepage that the add-on will modify search provider configuration, few people get to read that fine print because they get the app from alternate sources that conceal this fact. This unethical tactic will be covered further down.

The real gist of 1 Click PDF app for Mac doesn’t live up to its marketing

One more concern about 1 Click PDF app is that every file that’s subject to conversion is uploaded to the vendor’s server. The claims that these objects will be automatically deleted in an hour are a cold comfort, because it’s impossible to know for sure what the app authors actually do with that information. It’s quite possible that they supply it to third parties, such as advertisers or even cybercrooks who take advantage of it by pulling off identity theft or orchestrating phishing campaigns. Another fact to take into account is that the potentially harmful program may collect details on the victim’s whereabouts, Internet history, IP address, version of Mac OS X or macOS they are using, and the like. If the entirety of this personally identifiable data is compiled into a single source, that’s a powerful instrument to deploy targeted attacks against an individual or organization.

1 Click PDF virus can be both dangerous and annoying in a slightly different way, too. It displays obnoxious ads in Safari, Chrome and Firefox on a Mac and redirects the browser to arbitrary websites, not just the search engine referenced on the official product page. The landing resources can be anything, from sites full of sponsored links to malware download hubs. In particular, the culprit may forward the victim’s traffic to tricky web pages that push MacKeeper, a sample of Mac scareware that reports fake threats and insists that the user buy its license to apply the “fix”. All in all, given the adverse characteristics of the 1 Click PDF application, the format conversion feature appears to be a smokescreen that cloaks wicked intensions. To top it off, it can be a launchpad for installing more malware onto the Mac.

Getting back to the distribution quirks mentioned above, the program in question is rarely downloaded from its nifty-looking home site. Instead, most people get it from bundles of free apps that deliberately veil the presence of the dodgy code so that the victim is clueless about the changes that will take place. Since the installation of 1 Click PDF isn’t always an informed decision, it raises a red flag just like commonplace adware does. When a user realizes that their browser has been affected and tries to rectify the settings in the normal way, these attempts are going to be futile because the perpetrating program is designed to resist regular uninstalling. An effective way to circumvent this persistence is covered in the follow-up sections of this entry, so read them carefully and stick with the recommendations.
