PUP.Optional.Yontoo Removal [Explained]

What is PUP.Optional.Yontoo

PUP.Optional.Yontoo is a detection name used by some anti-virus programs to detect adware that belongs to a certain adware family. If your anti-virus is detecting it on your computer, you’re likely constantly bombarded with advertisements when browsing. The constant ads and random redirects make adware a very noticeable infection, even without anti-virus software. While many users may refer to adware as a virus, the classification is not technically correct. Adware is relatively harmless by itself since it mainly focuses on showing ads. Said ads, on the other hand, are a different story. Adware generated ads could expose you to potentially dangerous content, including various scams and malware. So if your anti-virus software is detecting it, allow it to delete PUP.Optional.Yontoo.

If you notice adware present on your computer, you’re likely confused about how adware installed in the first place. Adware, as well as other smaller infections like browser hijackers and potentially unwanted programs (PUPs), use software bundling to spread. What likely happened is adware was attached to a free program you installed and you did not notice. To prevent it from installing, you’d need to have deselected it during installation. Because it went unnoticed, the adware was able to install.

How to prevent adware installation in the future

As we said above, you likely infected your computer with adware when installing freeware. Most free programs come with additional offers attached, usually adware, browser hijackers and PUPs. The offers are optional but they are set to install by default, so to prevent their installation, you’d need to deselect them. The offers are purposely hidden, which results in users not noticing them and accidentally allowing them to install. Fortunately, it’s not difficult to prevent these installation, as long as you pay attention to how you install programs.

During installations, opt for Advanced (Custom) settings when given the option. Default settings will conceal all offers and they’ll be able to install alongside. In Advanced, however, they’ll be made visible, and you’ll be able to deselect them. All you need to do is uncheck the boxes of those offers. Once you have deselected all offers, you can continue installing the program.

Keep in mind that most free programs come with additional offers. Your computer will be full of junk programs if you allow these offers to install freely.

What does adware do?

The main purpose of adware is to expose you to advertisement content in order to generate revenue. This means banners, pop-ups and most annoyingly, redirects. The adware can attach itself to all popular browsers, including Mozilla Firefox and Google Chrome. Once it hijacks the browser, you’ll be bombarded with ads all the time.

We mentioned that adware itself isn’t particularly dangerous. However, the ads that it generates may actually be harmful. Adware is known to show ads promoting fraudulent programs, fake updates, as well as those “You have won” and tech-support scams. Thus, interaction with ads while adware is installed should be avoided.

You may be shown a fake virus alert claiming that your computer is infected with a serious virus that is stealing your information. The fake notification will either ask you to install the offered program, or call the provided number for supposed tech-support. Since these virus alerts are always fake, you don’t need to install anything or call anyone. If you did download whatever is offered in those ads, you’d end up with some kind of infection. And if you were to call, you’d be dealing with professional scammers aiming to get you to pay for useless services. Legitimate virus alerts will only come from your anti-virus program, not your browser.

If you haven’t already been aware of this, all those “You have won” ads will always be fake. Every single one of them. Those scams offer tech prizes, such as iPhones, Samsung smartphones, tablets, computers, etc., which can be quite tempting for more gullible users. However, these ads are merely scams that want your personal information.
