Cannot use my browser – ads all over the place!

The internet is a wonderful thing, there’s an endless variety of possible benefits that we can extract from it. However, in order to access the World Wide Web, we all need those specific programs called browsers. Without them there’s almost nothing we can do to utilize our connection to the Internet. That’s why it is essential that our browser is working properly and effectively. Most browsers are doing their job just fine. Furthermore, each day these programs are becoming more and more advanced so that they can provide you with the best online experience possible. Often, a way to enhance your browser’s effectiveness is to install different kinds of add-ons. For the most part those can be very useful. Unfortunately, there are some of them that are the polar opposite of what they’re supposed to be. You see, there’s a specific type of browser extensions that instead of improving and expanding your browser’s capabilities, it’s actually crippling them. This type of unwanted programs is called adware and it is notorious for its intrusive and annoying behavior. If you’re currently reading this article, then the chances are that you’ve had “Mass Sea” installed on your computer, which is one of the latest of adware programs out there.

Some more info about adware and Mass Sea “Virus”

Many people mistake adware for a computer virus. This is certainly the case with Mass Sea “virus”, as most of our readers like to refer to. This is not entirely correct though – Mass Sea “virus” is not actually a virus. As we already said, adware is a specific kind of browser extension that tends to heavily obstruct your online experience. It does that by filling your screen with various types of online adverts as soon as you attempt to access your browsing program. If you’re seeing different sorts of pop-ups, box messages, banners or page redirects being displayed on your screen while browsing that don’t go away, no matter what site you’re visiting – then you’re almost certainly dealing with “Mass Sea” or other adware. Here, we need to make it clear that adware programs are not categorized as viruses. Instead, they fall under the PUP (potentially unwanted programs) category. The difference between malicious viruses such as Ransomware or Trojan Horses and PUP’s is quite distinguishable. While the former are created with the sole purpose of serving cyber criminals’ illegal agenda, the latter are basically regular programs that are deemed unwanted due to their intrusive behavior and general uselessness. With that being said, we should still warn you that “Mass Sea” and adware in general may still hide some potential security hazards. It’s usually their ads that may expose your PC to possible threats, such as the aforementioned Trojans or ransomware. That is why you are advised to avoid clicking on any of the pop-ups. Sometimes clicking on an ad might redirect you to an illegal and maybe even virus-infested website. Thought this happens rarely and most ads are safe, there’s no need to risk your system’s security in such a manner. Besides, most ads are there with the sole purpose of generating clicks without providing you with anything useful in return. In fact, the whole idea behind adware is that for every click an ad receives, the intrusive program’s developer gains revenue (the pay-per-click method).

You’ve actually installed “Mass Sea” yourself!

That’s right – despite there being quite a few methods for spreading adware like spam e-mails or file-sharing sites, in most cases it’s the users’ lack of vigilance that gets the adware installed on their computers. You surely don’t remember how it happened, but we are pretty certain that you actually installed “Mass Sea”. This happens via the program-bundling method of adware distribution. When this method is being utilized by the PUP’s developer, the unwanted program is bundled with another third-party program that is usually cheap or free.

  • This doesn’t necessarily mean that this other program is poorly developed. It’s just that big companies that create expensive software don’t usually need the extra income from signing contracts with adware developers.

Once you install that cheap or free program, if you’re not paying attention to the details, you also get “Mass Sea” along with it. That is why you should always opt for the advanced/custom settings when attempting to install new software. Doing that would allow you to see any content added to the main install. All you have to do then is uncheck everything that you think might be adware or any other type of PUP. After doing so, you should be okay to carry on with the installation of the actual program.

Now, if you’re looking for a way to get “Mass Sea” uninstalled and removed from your machine, we have prepared a guide for that just below this article. Our advice for you is to get rid of the intrusive software as soon as possible. The guide is detailed and includes images, so you should be able to deal with that issue yourself without the need to call in an IT professional.
