Pup Virus

Potentially Unwanted Programs (PUPs) are software programs that you had no intention of downloading. The PUP virus, also known as a Potentially Unwanted Application (PUA), junkware, or bundleware, mostly come with software that you planned to download. This virus software gets installed in your system when you click on an installation without reading the fine print, thus agreeing to these extra applications. The only way to clean your PC and prevent such PUP virus attacks is to install and use a good antivirus software that will help in providing an efficient virus scanning and virus removal process.

However, to be extra cautious of what you are clicking and avoid unnecessary downloads, you will have to be aware of a few key signs that indicate that you have a PUP virus on your computer:

  • Website links get redirected to websites that the user had not intended to visit.
  • Browser pop-ups will recommend false updates or other software.
  • Advertisements appear in unwanted places.
  • Unwanted programs could get installed without the user’s knowledge.
  • Web browser’s homepage suddenly changes without the user’s permission.
  • Web pages regularly visited by a user do not get displayed properly.

How Does PUP Virus Enter Your Computer?

PUP virus enters your system through download portals, and the only way to prevent such a scenario is to focus and download files by using a good antivirus software. This virus removal tool will need to enable the PUP virus Detection feature that will help in verifying the file name and analyzing whether it is the correct software. Besides entering via download portals, the PUP virus also makes their entry through several other techniques. One such technique refers to “Dark Patterns,” user interfaces designed to trick people. One simple example of a dark pattern refers to a newsletter in which you find it difficult to detect the unsubscribe button.

How to Prevent the Entry of PUP Virus

The entry of the PUP virus into your PC can be prevented by adopting the following measures:

    • Carefully reading through EULAs
      The End User License Agreements (EULAs) that come with any download are legal contracts between you and the developers of the software programs you desire to download. Most people skip reading these legal contracts and straightaway click the “I accept” button. Many of us don’t understand that EULAs are used as targets through which the developers of a PUP virus can legally slip their programs onto your PC. To avoid such a scenario, we should never accept terms of use that are meant for bundled programs. Always read the top title above the fine print just to make sure that the EULA you are accepting is only for the program you initially downloaded. However, you can always decline it and still move on with the installation process in case you find any discrepancies later.

    • Fake updates
      Sometimes, you could come across updates frequently pushed via temporarily developed websites that mostly serve Open Source software, enveloped in downloaders that remind users to update their Java, Service Pack, Flash Player, etc. There are several companies that develop huge numbers of websites every day just to trick the user and create traffic to their website. The best solution for this issue is to click “Decline” and then untick the checkboxes, if any.


    • Take time to clearly read install wizard instructions
      After downloading a particular software, an installation wizard will take you through the whole installation process. The install wizard here refers to a series of dialog boxes that guide you step by step through the whole installation process.The PUP virus is capable of hiding in the install wizard because their developers understand that most users just skim through the installation steps while launching their intended program. To protect your PC from a PUP virus, refrain from accepting express, standard, default, and several other installation settings that are recommended. Make sure to always choose custom.


    • Boost up PC security
      It is highly recommended that you get valuable assistance from cybersecurity and antivirus programs.
