removal by Olivia Morelli - - | Type: Adware

Can you tell me why I am constantly being redirected to suspicious domains that begin with “View.contextualyield.com” URL? It is so annoying, and I do not know how to fix this. Can you help me out?

General information about Contextualyield:

Contextualyield belongs to an adware software category. This program can cause numerous different unpleasant effects on the infected computer. If this program succeeds to enter the computer system without your knowledge, it might easily trick you into tricking that your computer has many issues, because Contextualyield displays annoying web ads that commonly offer to update software, scan your computer for threats, contact tech support and so on. These Contextualyield ads usually show up as New Tab pages or pop-up windows that can appear out of nowhere.

ads by Contextualyield adware

However, you should not believe anything that Contextualyield scam commands you to do. It is just a potentially unwanted program (PUP), which is a computer problem itself. This program gains pay-per-click or pay-per-install revenue from third-party companies. Sadly, the majority of Contextualyield ads promote deceptive programs that pretend to be legitimate programs’ updates, while in reality they can be dangerous computer threats. You can never know what kind of software Contextual Yield promotes, so you should not rely on its offers or click on them. Otherwise, you may experience Contextualyield redirects to dangerous websites or install a computer threat unintentionally.

Questions about Contextualyield virus

What is more, Contextualyield virus can obtain information about your online browsing experience, and share it with its third-party affiliates. It can steal data such as browsing history, search queries, computer geolocation, IP address and so on. We do not recommend sharing such data with doubtful sources. Moreover, if you want to entirely secure your computer from Contextualyield and similar spyware, you should install an anti-malware software like Reimage (you can use any other professional anti-malware program as well), and scan your computer with it. Reimage can find and uninstall spyware and malware with ease.

How does Contextualyield hijack computers?

Contextualyield usually reveals its existence because it usually signs its ads with such texts: “ads by Contextualyield,” “Contextualyield deals” or “by Contextualyield.” Obviously, you want to know how this adware program has landed on your computer without your consent. The problem is, Contextualyield PUP is spread together with other free programs as an attachment. Therefore, not all computer users might notice it because the majority of PC users tend to install programs without paying attention to the software installation setup. People tend to install programs by continuously clicking “Next,” “Agree and Install” buttons until the installation process is finished. Wrong! You should NOT install programs this way because you might get infected with spyware or malware this way. Free programs frequently promote third-party software, and to refuse to install such additions you need to set “Advanced” or “Custom” installation settings. Then, the setup should provide a list of “optional downloads.” Opt these suggestions to install free apps out.

Contextualyield hijacked your computer already? It is not a problem! You can easily fix this computer issue by removing this adware program from the system. To learn how to do that, continue reading on the further page.
