Dear reader, if you are reading this article it’s properly because your computer has been infected with PrintOnKey Ads and you would like it removed. We’ll help you take care of that. But this article has another very important goal – to teach you how to recognize viruses like PrintOnKey Ads before they infect your computer.


Nearly all common viruses rely on the human factor – that is they prey on the user’s ignorance, who will install them thinking they are something else. Seeing them for what they are is therefore the best defense their is.

First lets look at how PrintOnKey Ads operates

PrintOnKey Ads is classified as an Adware, because generating unwanted ads in abundance is what these viruses do. Besides the usual ads you may also be seeing quite a few other unwanted messages. These may include:

  1. Error messages claiming that you need to install a missing plug-in.
  2. Offers to download free programs. Anti-Malware apps are commonly used as bait here.
  3. Urgent warnings to fix security vulnerabilities by downloading an update to some program you already have like Flash or Java.
  4. Media windows that demand some Video Player installer before showing the video.

Yes, as you have probably guessed all of these are viruses. In fact these and similar messages are one of the most common ways adware and malware use to spread. You should NEVER download and install .exe files from untrusted sources. In the off chance that you do think some program needs to be updated or you want to download some free program – simply google what you need and look for the official site. That way you can be sure the downloaded file is virus free.

Some other tricks virus creators might use to fool you

On download sites and torrent sites there are often multiple download buttons shown. Out of these only one will be the real one (if there is a real one at all). All the rest will actually download a virus. IMPORTANT! Note that the virus may carry the same name as the file you want, but the extension will always be an .exe for the virus. NEVER install .exe files you havn’t gotten from the official dealer.

Another trick is the so-called program bundles. These days it’s common practice to include one or more addition application to a program’s installer. These additional programs are there to promote other products of the company or products of partners. Unfortunately this is often abused, especially with free programs. The added extras may be adware. That’s why its wise to always use the advanced installation feature. It gives you exact control over what is getting installed. Forbid access to all extras you don’t really want or need. You will ALWAYS get the main program regardless of how the installer is worded.

Once it opens, choose the Processes Tab. Look at all of the processes in front of you and try to determine which ones are a virus. Google them or ask us in the comments and we will provide the best assistance we can. If the virus returns later on, the reason is that you missed something here.


Right click on each of the virus processes separately and select Open File Location. Also, End the process after you open the folder. Just to make sure we don’t delete any programs you mistakenly took for a virus, copy the folders somewhere, then delete the directories you were sent to.

    HKEY_CURRENT_USER—-Software—MicrosoftWindows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft Internet Explorer—-Main—- Random
