What is is a class of programs that are designed to provide you with information in the form of advertisements. Such programs are being classified as adware. Do note that as it is not programmed to cause any harm, it is thus legal and is not considered as a virus. A virus is a piece of programming code that is malicious and cause harm to the computer in question. Viruses also tend to be self-replicating and will try to infect all other devices that come in contact with an infected PC. Adware, in comparison, is comparatively harmless in terms of system health and security., after being installed onto your computer, is able to function on any or all of the browsers in your computer, be it Firefox, Mozilla or Internet Explorer. Thus, changing between the browsers will usually not solve the issue. It is designed to be able to track your browsing patterns and history, favourites and bookmarks. After the initial stage of gathering information, it will then generate believable ads that are specially catered to your preferences. These ads may appear in the form of banners, pop-up ads and boxes or even as a separate window. They may feature coupons or deals of items or proclaiming that you have just won a lottery. All these ads are designed in such a way to entice you to click on it which you are highly encouraged to avoid doing.

Why should I not click on the ads?

After clicking on the ads, you will be directed to a third-party webpage. These webpages may vary in terms of the level of security threat that it poses. The most harmless page you can be directed to will be that of a previous webpage you have visited where the deal might be featured. Another relatively harmless page that you might be directed to is the third-party pay-per-click sites that allows the creators to earn some income when people, like you and I, visit the site. Some harmful pages might be those that doubles up as a portal for other adware to enter your computer without you knowing. There are also pages that prompts you to download a certain software. These programs often tend to be of low quality, or may have undesirable features such as weak security or other problems..

Why should I uninstall

Other than having to constantly avoid the numerous ads that it creates, the particular adware will also cause your computer to slow down as it is a program in itself and will take up valuable processing space to run.

Also, over time, the incessant number of ads might cause you undue amount of irritation, annoyance, frustration as well as stress. All of which can easily be avoided by removing

How did my computer get infected in the first place?

According to our research, there are a number of ways in which people get infected by this pest, – just as much ways as there are to perform Yeabests removal.

The most common way is through downloading one of the many free and illegal programs that are widely available on the Internet. This is where the adware is being tied together with the program as a bundle. When downloading the program then, the adware will also be downloaded together without you knowing. This process is known as bundling.

In such cases then, exercise caution when going through the installation process. Opt for the “Custom Installation” so that you are able to vet through the names of the files. Uncheck any ones that seem unfamiliar to you.

Another way in which you could have gotten infected is when you open up emails from unknown senders. When you see emails from unknown senders, do not open the mail. Instead, direct it straightaway to your “Junk Mail” folder. It will also be prudent to configure your mailbox settings such that it will direct similar mails straight to the “Junk Mail” folder in the future (or do it yourself)


Type Browser Hijacker
Danger Level Medium (Various undesirable Ads will fill your screen and distract you from work)
Symptoms The Ads themselves are the most prominent symptom, although you may also experience other annoyances such as having your search engine changed.
