Dear User,

In case you are really interested in the following information, you could have become a victim of some probably undesired, but still very stubborn ads that keep popping up while you are surfing the Internet, no matter which of your browsers you are using – Opera, Chrome, Explorer, Firefox or others.

The programs that generate such ads are referred to as Adware and the one that is currently irritating you is popularly known under the name WeatherBlink. What we can do for you is provide some essential details about the annoying software, as well as a carefully assembled removal guide and some general prevention tips. We strongly recommend that you pay attention even to the smallest details in that article to become fully prepared for solving your technical issues.

Does Adware equal “advertisement + software”?

The software that is known to display plenty of ads in various shapes, forms and colors is called Adware. The word stands for advertisements and software, as you might expect. Below you will find details about the distribution methods, ways of removal and possible negative sides.

You are likely to come across such ad-producing software when:

  1. Most often when you download and install a free program from the Internet. Free software gets distributed in software bundles together with different versions of other software, most commonly Adware-like programs. In fact, it doesn’t matter whether Adware is included in the shareware bundle you download or not. It only matters whether you will allow it to enter your PC. Many people unknowingly and naively let it infiltrate their machines by installing new software in the Default (Easy, Quick, Automatic) way. If you don’t want an infection to occur, forget about that installation option. The only one you should use is the Advanced (Custom, Manual) one.
  2. Adware may also come via spam emails and their attachments, torrents and already infected websites. It is also possible for you to be redirected to Adware-based products through hyperlinks that you habitually click on.

Adware – a friend or a foe?

No matter how it is distributed, Adware represents nothing malicious. It may often be mistaken for a virus because of the shady methods it uses to get to your system. However, remember the fact that such ads-generating programs are NOT created to steal any information from you, to harm your PC, block any files there, blackmail you for money or lead to the destruction of any data, like is the case with widespread viruses such as Ransomware and Trojans.

The only aspect of their behavior you should be concerned about is the possible irritation they tend to cause. The production of so many ads does not just serve to annoy you – it earns money for the developers that include such scripts in their bundles. The infamous Pay Per Click scheme is involved here and the more advertisements are shown, the more money is generated.

In general, the known Adware-like products cause NO serious technical issues! However, to be completely precise, we are going to mention the worst potential effects of Adware on your machine:

  1. There might be some developers who research your preferences – the Adware they develop is programmed to enlist all your movements, while surfing the web. Such data is later used for customizing the displayed ads to match your recent searches and personal interests. It is even possible that this information could be sold to 3rd parties.
  2. Some of the generated ads might be able to redirect you to suspicious places on the web with potentially malicious content, like Ransomware.
  3. The amount of system resources Adware-based programs consume in order to show those numerous ads may be so big that your computer may sometimes freeze or become unable to function properly. Such a scenario is highly unlikely, though.

The aforementioned possible negative consequences of Adware contribute to its rather bad image and many security vendors have already referred to it as a PUP {potentially unwanted program}.

When we talk about WeatherBlink in particular

WeatherBlink, as an exemplary type of Adware, works in the following way: 
As soon as it has found its way into your system, it begins to show numerous ads in many various forms. Most typically, it comes from within a software bundle and gets installed in a stealthy way. Also, it may use your browsing history to determine what offers, products or services you need or may be interested in.

If you want to permanently get rid of that program, you will be happy to know that we have created a detailed removal guide to help you complete that task in a successful way.
