The nature of programs based on Adware

All the software, programmed to generate various online advertisements like banners, tabs and pop-ups, usually affects the most popular browsers that you may have downloaded, such as Chrome, Firefox, Explorer, Opera. Such programs, including GubZL “Virus” – the one we are going to elaborate on in the paragraphs that follow, could be extremely irritating and might appear to be intrusive to some users. As a program identified as Adware, GubZL “Virus” can become a part of your browser and start producing many annoying ads. However, please note that we are not talking about a type of malware here. No Adware is a virus. Normal viruses like the ones based on Trojans or Ransomware typically perform some really damaging and dangerous activities while on your PC. Their possible effects could include destruction of files, corruption of sensitive data, identity theft, a slowdown of the entire system, encryption of important files, spying on and stalking you as an individual. Nothing like that is typical of any ad-broadcasting program. Don’t be worried, it is a harmless type of software with annoying effects, but nothing more.

Why might the programs based on Adware produce so many ads?

All ad-broadcasting software is completely legitimate. Such programs appear to be the result of the mutual work of both goods producers and software developers. The ones who order such software are manufacturers and providers interested in promoting what they produce and offer. The ones who create GubZL “Virus” and its sibling programs are the programmers, who are interested in making some additional profit. These contracts are legal and ensure that promotion of goods will happen through ad campaigns on the web. This is an advertising technique just like those you see on TV or hear on the radio. In case you are wondering how exactly programmers get paid, this is according to a business model based on the number of the produced and/or opened banners, tabs and other types of ads. This is a strategy more commonly known as the pay-per-click scheme.

How is it possible to contract Adware like GubZL “Virus”?

What bothers users around the world most is basically the way such ad-generating programs get around. Their means of distribution could be quite shady but they get inside someone’s system only with this person’s personal approval, no matter whether it is informed or uninformed. Most of the time users install such software unknowingly and then wonder how on the Earth they have been infected with Adware. The best sources of GubZL “Virus” are the following:

  • GubZL “Virus” could come as spam emails, either within links in the letters themselves or as an attachment.
  • All Adware-based programs could be incorporated in contaminated websites and video and torrent-sharing pages. You can get one from there.
  • In some cases Adware might come as a drive-by download that you have no idea has happened. This happens when you open or click on something contagious and get that disturbing program in return.
  • GubZL “Virus” mostly comes in bundles. Bundles are several different programs assembled and distributed together, usually for free. Any bundle might consist of ad-producing software, games, various apps and new programs. However, just downloading such a bundle won’t result in an infection. Most of the problems with Adware-type programs occur when the bundles that include them are not properly installed.

What is the safe way of installing GubZL “Virus” on your machine?

In case you do want to use something from a bundle, make sure that you incorporate that bundle into your PC in the correct way. By the correct way we mean by selecting the wizard installation feature that gives you control over the entire installation process. Such options could be the Custom and the Advanced one – they will give you the opportunity to select or deselect the products from the bundle that you need or don’t really need. Remember: no Quick or time-saving installation feature will do you any good. Don’t fall for the Default installation trap. Be wise, avoid all such features. However, the best way to solve a technical problem is to avoid its occurrence. Please, make sure you keep your distance – don’t use or visit suspicious online locations and don’t download anything from shady sources. In case you would like to remove GubZL “Virus” for good, follow the Removal Guide we have provided below.
