What kind of program is

Now, to start with, we know that you are most probably afraid you may have caught some nasty virus. That’s why we will first clarify what kind of program has made its way on your PC. is an advertising-oriented program that falls under the category of browser hijackers. This program is created with the idea of displaying huge amounts of advertisements on your screen in the hope of you clicking some of them. This way, your clicks will generate income for its developers who earn from the infamous Pay-Per-Click scheme. In fact, the main purpose of this type of software is to earn money through this scheme. That’s why it is widely distributed on the web through software bundles, installation managers, free software installers, torrents, spam emails, open source download platforms and many more. Users usually don’t notice it when it gets installed, because it comes along with other software they willingly install. When running the setup they make a common mistake by clicking the standard installation and skipping the advanced option in the bundle. This is how they mostly end up with such programs on their PC.

There is hardly anything useful for users, who have browser hijackers installed on their system, except for the unstoppable ads, pop-ups, and banners that appear on their screen. Their searches usually get redirected to sponsored web pages that the vendors pay for to get traffic and clicks. Unfortunately, sometimes this activity may seriously interfere with the normal web activity of the users. In such cases, many people prefer to uninstall the browser hijacker in order to save themselves from the intrusive advertisements. vs viruses

Let’s begin by stating something that may seem strange to you – is not a “real” virus. In general, there are two types of programs that may cause some disturbance to users – the malicious ones and the potentially unwanted ones. The malicious programs such as viruses, different harmful scripts like Trojans, Ransomware and Spyware represent a serious security risk to every computer. They are illegal pieces of software, created by cyber criminals with the sole aim of performing a huge arsenal of harmful activities on the infected machine. Data theft, file corruption, system crashes, credential stealing, spying and blackmailing are just some of the activities a malicious infection similar to Ransomware could do. The potentially unwanted programs (PUPs), on the other hand, are mostly legally developed pieces of software, which do not intend to harm your computer in any way. However, they still may cause some potentially unwanted side effects or questionable activities. This is the case with the browser hijackers. Many people, who are not really sure what is causing the strange changes in their browser, may think that is a virus or some kind of malicious program that has taken over their computer. But they should not be worried about their system because this program itself cannot harm it in any way. However, there are some PC issues that may give them a good reason to uninstall the browser hijacker and here are some of them:

  • The speed of your computer and particularly the affected browser may be greatly reduced.
  • Your browsing may be constantly interrupted by irrelevant or undesired ads.
  • You may land on useless or insecure web pages.
  • Your browsing activity may be monitored and transmitted to third parties for profit or analysis.
  • Your PC screen may freeze due to the enormous amount of advertisements and new tabs.
  • Your system may spontaneously shut down or crash due to high CPU usage.

Having said this, it may be better for your computer to remove before you start experiencing all of its undesired side effects. This page offers a removal guide that will help you do this in just a few easy steps. Please follow the instructions below to effectively uninstall and all its traces. For extra support, we suggest you use the professional removal tool, which will deep scan your system for any leftovers.
