You have probably already understood that CompareNBuy is another misleading application that is promoted as Amazon discount finder and tries to trick people into installing it by the promises to help you save time and money. Unfortunately, we have to disappoint you because a reliable money and time-saving application that would work in this way hasn't been designed yet. Even though Internet is full of such and similar programs, you should never ever trust them because most of them, if not all, are categorized as adwares and a potentially unwanted programs (PUPs). Even though that from the first glimpse CompareNBuy plug-in seems as a genuine shopping helper, you should be aware that it may try to redirect you to unknown websites, collect certain information about you, try to install another adware on your computer and implement a whole list of unfair activities behind your back. Usually, CompareNBuy virus travels alongside popular free software, such as download managers, video streaming software, PDF converters and so on. Wen users do not pay enough attention to the installation process of a freeware, they inadvertently accept to install various additional programs and later experiences various unwanted issues. If CompareNBuy gets inside, it starts delivering tons of annoying ads regardless of the content of the websites that you visit. If you want to keep your PC secure, we recommend ignoring 'Ads by CompareNBuy' due to the fact that by clicking on them you may be rerouted not only to unknown websites, but also to unsafe ones. In addition to that, you should remove this adware ASAP because it may collect your browsing habits and monitor your online activities daily.

How can CompareNBuy hijack my computer?

Due to the suspicious activities that it can implement on target computer, it has been labeled as an adware and potentially unwanted program (PUP). If you haven't dealt with such a program before, you should be aware that PUPs rely on misleading distribution method that is called 'bundling'. It allows combining several programs and distributing them in one pack. Even though this method is legitimate, it is mainly used for spreading various unwanted programs and security experts assert that this method should be forbidden in order to decrease the number of computers infected by viruses or malwares as well. We say so because adware and browser hijackers are treated as a backdoor for malicious programs due to the fact that they may try to redirect users to unsafe websites filled with questionable content. Fortunately, you don't have to stop installing and using free programs to avoid adwares on your computer. What you have to do is to spend more time on the installation process of a freeware. You should always select Advanced or Custom installation option and carefully look for inspect every check box carefully.
