This page aims to help you remove Virus. These Virus removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

Browser Hijackers are a type of programs that are generally regarded as unwanted, because of a number of unpleasant traits that they oftentimes possess. Here we will be talking about Virus, which is a newly released program that shares similar characteristics with the Hijacker type. Many users have been complaining about the program’s tendency to get onto their Firefox, Chrome or IE browser and get it covered with new search engines, toolbars and sometimes even cause unpleasant page redirects and change the homepage of the browser. Though usually not malicious, such program behavior can be heavily obstructive and unpleasant for anyone unlucky enough to have landed Virus, which is why, apart from giving you some essential information concerning this program, here we will also show you how you can uninstall it from your machine. You can find the instructions on how to do that down below in our guide on how to remove Virus.

Hijacker, viruses and Virus

It is easy to mistake Virus for some sort of noxious Trojan horse or Ransomware virus. After all, the program is known to implement changes to your browser without asking for your permission. This can certainly be quite unnerving but keep in mind that as long as you are being careful around the unpleasant software, everything should be just fine. Contrary to what many people might think, Browser Hijackers such as Virus are quite different from real PC viruses (Trojan horses, Ransomware, etc.) and here are some of the main differences:

  • In contrast to viruses, Hijackers are generally not trying to harm your machine and they are not known to mess with any personal user files.
  • Additionally, a lot of Browser Hijackers are actually legal, even though they might be considered unwanted. Malicious viruses are never legal.
  • Another important difference is the fact that unlike Trojans and Ransomware, Virus ant other Hijackers are not trying to remain undetected by the user. In fact, the whole purpose of those programs is to actually be noticed since they are usually used as online marketing tools, therefore, the more conspicuous they are, the better.

The problem with Hijackers

Getting your browser invaded and heavily modified is but a fraction of the issues that one might have with a Hijacker program. Here, we will give you several other examples of what a program of this type can cause to your machine. Again, this does not make Virus a virus, but you should still be well aware of the potential negative effects that such an application might have on your system.

  • Oftentimes, to add to the unpleasant browser changes that the user experiences, Browser Hijackers might also fill the browser with obnoxious and obstructive banners, pop-ups and other forms of aggressive online ads.
  • The aforementioned ads are commonly enhanced by information extracted directly from your recent browsing history, thus making them more look appealing and relevant to your individual interests.
  • In some cases, in an attempt to make your browsers more susceptible to unwanted changes, some Hijackers will make unauthorized modifications to your system’s registry, which can potentially leave your machine exposed to different online threats.

Ways of fending off Virus

The next list of tips is very important for you to remember and employ from now on. It will not only help you protect your machine against Hijackers but it will generally make your system safer and more secure against other potential hazards as well.

  • If you end up visiting an obscure website filled with a lot of big and colorful banners and hyperlinks, it is probably better to leave its pages, since this type of sketchy sites are commonly distribution hubs for Hijackers.
  • Spam e-mails can not only be annoying but they can also be used for spreading unpleasant software programs such as Virus, so be careful what letters you open the next time you are checking your email.
  • Some browsers have an automatic download function, which you should generally disable if you want to get some extra protection for your PC.
  • A reliable anti-malware tool is always a good thing to have around – it can help with Hijackers too!
  • Before you install any new programs (especially if they are free), be sure to check their installation menus and see if there are any applications bundled with the main piece of software. If there are indeed added programs, it is advisable that you look them up and if any of them turn out to appear potentially unwanted, uncheck so as to leave them out.
