How Does (4) Four Virus Spread

The (4) Four virus can be spread via any type of software which is causing browser redirects on your computer. Usually, most often these are browser hijacking PUPs (Potentially Unwanted Programs). They aim to attach to your web browser and your computer as a suspicious browser extension or a program installed directly. They are usually installed via either another adware on your computer or via bundling. Bundling is a form of pushing the (4) Four virus software on your computer via adding the app that is causing redirects to it in the software setups of a free program you download online. This could be your favorite free torrent program, media player or any other free software.

In addition to this, you can receive a redirect to this website by simply visiting a suspicious URL which may cause a browser redirect as a result of having a script embedded in the website itself. Some sites go as far as bypassing ad-blocking software and this is the main reason why even if you have an Adblock installed to be careful which websites you visit.

(4) Four Virus – Activity and Purpose

The main purpose of this scamming software is to display it’s message and alongside it instructions on how to convince you to download a rogue antivirus program. Such fake antivirus programs pretend to discover fake malware on your computer and ask you to pay money in order to remove it. Some, more aggressive ones may even steal your financial details while you are purchasing their licensed versions. The messages of the (4) Four virus are very similar to one another, but they usually vary in what apps they push you to download. This is because they exist in all shapes and forms. The (4) Four virus pop-up can be seen in Windows machines, MacBooks and Apple and Android smartphones as well. The most often met message is the Windows one, which looks like the following:

It tries to get victims to panic by giving ~5 minutes deadline timer to click on the button “REMOVE VIRUSES” and warns that if the virus is not removed, it may corrupt the important files on your computer. This message should not be trusted and if you see it, you should immediately close your web browser. The complete message is the following:

Your system is heavily damaged by (4) virus!
{DATE}
We have detected that your Windows 7 is 28.1% DAMAGED because of (4) harmful viruses from recent
adult sites,
If you do not remove the virus now, it will cause permanent damage to your system, corrupt your photos,
data, applications, etc.
Here’s what you NEED to do (step by step):
Step 1: Tap the button and install PC SmartCIeanup for free now!
Step 2: Open the app to fix your system now!
3 minutes and 0 seconds
REMOVE VIRUSES>>

The version for smartphones is very similar, however it differs from the fact that it prompts to download a free app.

For MacBooks the message is rather the same, only it prompts to download the Mac version of the suspicious software:

In addition to simply aiming to display the message to you, the malicious web links to which you may be redirected contain completely random names, for example c38bd2xzdd.xys. They may also have tracking technologies embedded within them that may install various different tracking technologies on your computer as well, such as:

  • Cookies.
  • Pixels.
  • Tags.
  • LSOs (Local Shared Objects or Flash Cookies).

These tracking technologies may be used by the cyber-criminals to track your:

  • Location.
  • Language.
  • Browsing activity.
  • Online clicks on the page.

They may also be used from the website to which you are redirected when you try to download the suspicious software and they may even collect what you have typed on the site, like your name, address, credit card number, security code and other crucial information without malware actually being installed on your computer. Those cookies can only be removed via a specific anti-malware software which is designed to deal with threats like the (4) Four virus redirect intrusion.

      Hello, Sandy

      If you keep seeing redirects related to this virus on your computer, the situation may be more complicated than it seems. Since such viruses create objects on your computer that reside under random names, it is often recommended to scan for and remove those objects intelligently and automatically, as what most experts would recommend doing. Here is one such software that can do the job for you and clean your PC without you having to reinstall Windows: sensorstechforum.com/spyhunter-anti-malware-tool
