What is Epw3 Pop-up? Is it a computer virus?

If you are reading this article, you may have had some technical issues with the If you are searching for the right solution when it comes to questions about how to identify Epw3 and how to uninstall/remove it – then you have come to the right place. We will even provide you with useful tips on how to avoid such problems in the future! Epw3 is considered a possible Adware product. This is an important note to make. Many people believe that Epw3 is a virus. However it has been confirmed that this is not a computer virus, but a possible Adware/Browser Hijacker.

Adware – characteristics

Let me begin with a brief explanation of what Adware stands for.

Probably, you have already heard of the term Adware. This is the name of advertisement-generating programs, designed to display ads on your computer screen. They may also redirect your search requests to advertising websites and collect browser-history data about you. For instance, the types of the web pages that you visit help Adware to customize the annoying banners, pop-ups, and pop-unders that it shows you or redirects you to. What makes these applications shady is that they may actually gather data about your browsing preferences without your knowledge and consent. Adware that collects data without your  permission should not be confused with Trojan-like spyware programs or viruses (malware), gathering personal or private information. Adware DOESN’T collect info about banking, passwords or accounts. However, it may be possible that your online preferences might be sold to 3rd parties.

How do we end up dealing with an Adware program?

These are the most common ways in which Adware can get onto your computer system:

  • Through free or cheap software or torrents
    Adware might be embedded into any freeware or shareware program. To be honest, this is a legal practice albeit somewhat in the grayish area. Advertisement-generating applications actually earn solid revenue that helps the companies that develop them to further proceed with their research and distribution of the freeware or shareware program. Actually, this is the reason why some programmers embed Adware scripts into their programs – generating advertisements is a very well-paid method to sustain one’s business practice. As a result, most of the time this Adware is everything but harmful – it is extremely annoying and irritating, but usually does not damage your system.
  • Through already infected websites
    When you visit an already infected website, the consequence may be the unauthorised installation of Adware on your computer system. Often your computer could be reached via any browser vulnerability, and programs that have been designed for stealthy installation might get Adware products that act in this way are often referred to as Browser Hijackers.

When you install that free software product on your computer or visit such an infected website unprotected, the Adware-generating browser plug-ins are installed as well. It should be noted that this unwanted program may be able to integrate with all popular browsers such as Chrome, Firefox and IE. A great deal of Adware programs are mild, while others may be rather hostile and might have some spyware capabilities.

Specific features of the Epw3 Pop-up

We have finally reached the sole topic of this article. As you are already aware of what Adware really is, you may have guessed that your system is compromised by an Adware product. Now we will discuss it as well as the possible solutions, linked to that type of programs.

Generally, has been created as a direct-marketing tool. The ads it generates might have a lot of different forms such as banners, pop-ups, pop-unders or links built within web pages or sections of the Windows interface. This Adware changes its behaviour based on the tracking history of  the web sites you visit, enabling it to display Ads relevant to your preferences.

Some Adware programs do not leave easily- they tend to cling to.  You might even have to reinstall your OS. It is better to avoid Adware than to try to remove it, and also- a lot easier.

Here are some basic tips about avoiding Adware ans Browser Hijackers:

  • Be careful with what you download. Invest in secure programs rather than in free bundles that might result into the crash of your whole system because of the possibly dangerous software embedded in them.
  • Install a Firewall. Windows even has a built-in one. Keep it up-to-date.
  • Install a reliable anti-malware tool and keep it up-to-date.
  • Update your Windows frequently.

Always make sure that when you download new software and install it to your system, you choose the Manual/Customized Installation instead of the Default/Easy one. Watch out for unusual subprograms that come as a “present” and never let them make changes to your system.
