Experiencing a slow PC as of late? Are you getting sick and tired of pop-up advertisements coming out everywhere every other minute? Annoyed with the fact that your bookmark list is full of websites you didn’t add yourself? If you’re answer to all these questions is yes, then you are probably have been infected by adwares. And you have to do something about it as soon as possible before the problem worsen.

As you know, adwares refer to free softwares; also know as freewares or sharewares that frequently display advertisements on your desktop or web browser that came from one or more companies. These ads are usually targeted content based on your web surfing patterns and offer items or services you are more likely to have an interest in. Some adwares are installed to a computer system with the user’s consent, but most of the time, they are installed in the background without the user ever knowing it happening.

But what exactly do these adwares do when installed to a computer system? Is it really that bad for these “infections” to be running on your system without you knowing? What do they do to your computer and your computing experience? Let’s find out.

Though some adwares are safe and have no intentions of harming your computer, there are those that are used maliciously. It is malicious in a way that most of the time, these programs are being run on your system without you knowing about them. This is because this type of software is usually bundled with a freeware or shareware that a user have downloaded online and installed onto a PC.

After installation, adwares tend to become great threats to the performance of your PC and the information it contains in the hard drive. One thing it does is slow down the performance of the computer, using memory resources to be able to run the targeted ads it has. This constant displaying of pop-up advertisements may also slow you down when you are connected to the Internet. As a result, a person’s productivity is also slowed down.

Aside from slowing a system down, adwares also tinker with the settings you have on your computer. One example is that they change your web browser’s home page into something else. This is called hijacking. Some even add entries to the “Favorites” list without the user knowing about this. Usually, websites included are those of the companies the adwares are promoting. More advanced adwares also have the capability to redirect you to some other websites when doing a search on a search engine. All of these are possible because the program have already tampered with your system and other settings.

But the worst thing that can happen when your system gets infected by adwares involves your important personal information. Most adwares have the capability to track down a user’s computer and Internet activities, which includes but not limited to name, address, contact information, credit card number, etc. Afterwards, the programs can send these important data to a server where they can be used for even worse cyber crimes including credit card fraud, identity theft and others.

When adwares get out of hand, the also have the capability to prevent other softwares, including those that are used to clean them up, from being installed in your system. Anti-virus softwares and adware cleaners won’t be able to anything about the problem, which will ultimately result to having your computer reformatted altogether. This means extra expenses especially if you are not tech-savvy enough to perform the task yourself.

Though adwares may serve some purpose to software developers who offer their technology free of charge, they can also be used in very malicious ways by people who are set to do harm to other people. That is why it is very important to always be careful when installing freewares and sharewares to avoid further damages that can be caused by malwares such as adwares.
