Adfocus “Virus” Removal (Chrome)


In this article we are going to try and help you remove Adfocus “Virus”. Our instructions cover all Windows versions as well as most browsers – Chrome, Firefox, Internet Explorer etc.

Is Adfocus “Virus”, really a virus? Our article will help you deal with that!

Intrusive ads are all over the internet and everybody who regularly uses the worldwide web should know just how annoying they can get. There’s one particularly obstructive type of adverts that you can be faced with online. The ads we’re referring to are generated by a special program/browser add-on called adware. It should be noted, however, that for the most part adverts you see online are not caused by such programs. Most online ads are, in fact, integrated within the websites themselves. Therefore, there’s almost nothing that you can do about not seeing them anymore, apart from no longer visiting that specific site. Nonetheless, these integrated ads are not what this article is going to be focusing on. Besides, they are hardly as annoying as the adware-generated ones (the actual topic of our article). Ads generated by an adware will pop-up on every page you visit, regardless of the page itself. Furthermore, often they tend to show on each of your browsers, therefore, switching from one browser to another would be pointless. Many people begin to panic when they first see the barrage of ads flooding their screen, thinking that their computer has been infected with some kind of a malicious virus. This applies for Adfocus “Virus” as well. People often refer to Adfocus as a virus, when in fact this is not correct. Adware programs are unwanted for sure. They can be a real pain in the neck. However, it should be said that they do not fall under the virus category. First of all, adware are relatively harmless and despite their intrusive nature will hardly ever damage your system. Another important thing to mention is that they are usually legal programs distributed via legal methods. None of this applies to actual viruses (for instance Trojan Horses or Ransomware), which can both heavily damage your system and are undoubtedly illegal and illegally distributed. Ransomware in particular can lock you out of your files until you pay blackmail money. As you can see Adware is not all that bad, but there is no reason not to remove them either.

How to deal with it

If you’re currently dealing with the problem of having your browser filled with intrusive ads like pop-ups, box messages, banners and sudden page redirects, you can be pretty sure that they’re being caused by an adware type of add-on. Since Adfocus is one of the latest adware programs, it’s highly likely that this is the one that is currently residing in your system. Since most programs of that kind are almost the same and usually have no substantial differences between one another, we can safely assume that what applies to most adware will apply to Adfocus as well. As we already mentioned, adware are not dangerous as viruses are. Still, there are some things that you need to know about Adfocus and the rest of its kind.

First and foremost, some of the ads you see on your screen have the potential to put expose your PC to danger. Clicking on an ad may redirect you to an illegal and malicious page or further download more unwanted programs on your machine. This happens rarely and for the most part the ads are safe. However, we advise you to avoid clicking on them, just in case.

Secondly, if you ever get redirected to an unknown and shady-looking page, that you did not intend to visit, make sure yo quickly close it. Do not interact with those pages – just like some of the ads, such page redirects might hide potential dangers to your system’s security. Just click on the X button and you should be fine.

Thirdly, we will cover the most common distribution methods for Adfocus and how to avoid getting the intrusive program installed on your PC

  • Spam e-mails are a very commonly used method not only for distributing Adfocus, but all sorts of unwanted software. Usually spam letters go to in the spam folder. Still, it won’t hurt remaining vigilant even when checking your regular inbox.
  • Torrent and file-sharing sites are another obvious way via intrusive adware add-ons get distributed. If you want to download anything from such sites, remember to look at the torrent’s rating and download count. This usually helps you to distinguish the safe torrents from the potentially harmful ones.
  • The most successful method via which people get Adfocus on their computers is program-bundling. The intrusive add-on is bundled with another program. Once you download and install that program, you also get the annoying adware. To avoid that, simply opt for the advanced settings in the installation menu of the program you want to install. There, you should be able to see a list of any added content. Uncheck everything you may not want to have on your computer before proceeding with the installation. Note that Adfocus won’t necessarily go under the same name in that list. Still, it shouldn’t be hard to spot it and leave it out.

If you’re looking for a way uninstall and remove Adfocus from your system, read our guide on how to do that below this article.
