How to remove (uninstall) 1ClickPDF

Do you see aggressive ads on your favorite sites, labeled as “advertising by 1ClickPDF”? Did you see the name 1ClickPDF somewhere else on your workstation? If anything like that happened lately – the system is infested with an advertising utility, and our item was created to assist you to delete it.


What is 1ClickPDF

1ClickPDF, as you could guess already, is an advertising program. It’s a kind of tool that can do nothing useful, as it was made to achieve only one purpose: to irritate you. Surely, the driving-crazy stuff isn’t its direct goal, but you'll be annoyed in any case when adware does what it does – distributes the advertising content. It infests the computer, it alters the browser controls and delivers you lots of ads, making sure that they've attracted your attention. Fraudsters receive a little money for every click you're making, and now you realize why the banners appear again and again: it’s a gold mine. In the sections below, we will explain how adware got onto the PC and how it can be defended against similar threats. In case you know everything that you need on that topic and simply want to get rid of the virus ASAP – skip the coming parts and go to the removal advice.

Immediately after the infestation, 1ClickPDF modifies the settings of your browsers. It’s the best that it can do, because the main part of this adware is the scammers' search engine which takes over your browser when you download 1ClickPDF. So, 1ClickPDF changes the pre-set start page and your favorite search engine and places the scammer’s website in their place. Now you can't use the reputable Yahoo, Bing, Google or another search you like – you will browse the Net with the help of the poor scammers' search that shows ads fake results pop-ups and other suchlike trash. 1ClickPDF also alters the controls of browser shortcuts so that in case you return the default controls, you'll see the untrusted search engine in a first tab.

1ClickPDF can't be removed as a common utility, and if you attempt to do it - the adware will reinstall itself. It occurs thanks to the adware’s defensive mechanisms, and we will explain to you how they function:

  • A scheduled task is the simplest method to start the recovery of 1ClickPDF if the operator had erased it. Such tasks are not frequently utilized by regular PC operators, so the virus simply develops a task to confirm if it is running, and if it isn't – to download and install it one more time. The task verifies the 1ClickPDF's presence each time you reboot your device, and that’s why 1ClickPDF keeps returning.
  • Another method has the similar aim, but it employs the system registry and not the Scheduled Tasks service. You should clear the registry to beat this manner, but it’s a pretty hard thing for a newbie. The other registry values are needed for your device to function, and by deleting any of them, you may cause significant injury to the OS.


How 1ClickPDF was installed in the system

To make it simple, we’ll depict the process in total. 99% of the advertising utilities are each other's clones, replicated millions of times and transferred to third-grade web-criminals after slight visual changes. One of the suchlike lads purchased 1ClickPDF from the Dark Web, added their logo and uploaded it to file-sharing sites around the Web. And after that, there was you, downloading it. Wait, you're saying that you didn’t search for a program to drive you crazy? Possibly, you wanted some recipe to waste your system, and found a useful link to 1ClickPDF installer? Did we get it wrong again? OK, in that case, you sought for another tool that's really useful. Kind of a toll-free program from an unknown developer, or a pirated copy of some paid software you didn’t want to pay for.

This method is known as “sponsored installation”, and its essence is that hackers merge the installation files of a few viruses and a sole helpful tool to create one package. The essential feature of that installer is that they call it by the name of a helpful software, and you can't know which programs are there until the installation starts. On one of the middle stages, they give out a suggestion to download other viruses, with the required checkmarks placed and the mouse cursor already hovers over “OK”. And you pressed that button. There's another technique, with the “installation methods”. In most cases, the installation for experienced users means that customer can pick a folder for a utility to be established, and how many extra utilities do you want. In case of 1ClickPDF, picking the offered method of installation means that you allow all the adware from the package into the machine.
