I wrote this article to help you remove CompareNBuy. This CompareNBuy removal guide works for Chrome, Firefox and Internet Explorer.

If you suddenly encounter Ads by CompareNBuy on your monitor, it is a clear sign that the CompareNBuy adware application has already been setup on your PC. This is a browser add-on which is compatible with Internet Explorer, Mozilla Firefox and Google Chrome web browsers, so no matter which one you use, CompareNBuy could get installed on it.

The adware program will certainly try to convince you that it is very useful by providing you with multiple advertisements of products offered at discount prices. Nevertheless, the best thing you could do in this situation is to ignore all the ads promoted by the application and remove CompareNBuy from your computer as soon as possible. This is the only way to avoid any security-related issues.

Most often programs like CompareNBuy enter the virtual machine together with other free downloads. The installer of the extension is bundled with the installer of the chosen application, so when you install it, you also acquire the unwanted add-on and a bunch of other programs you had no intention to install.

You can avoid this from happening only by completing every setup step provided by the installation wizard of the new software. Remember to read all the information which is presented on your PC screen very carefully and opt out all the additional programs which you are offered for installation. In this way, your machine will be free from any potentially unwanted programs.

As CompareNBuy provides you with commercial advertisements, it is a typical advertising-supported application. As soon as it infiltrates your computer, the browser add-on starts performing some activities like connecting to Internet without any permission. In this way, the extension will have access to remote advertising servers where it will obtain all the adverts it provides you with.

Be aware that these ads are not generated by the browser add-on, but of some unfamiliar third parties. Thus, clicking on any of them might redirect you to corrupted websites where you might be lured to install malicious programs on your system. Considering this risk, removing CompareNBuy from your PC is strongly recommended.

Fortunately, the CompareNBuy removal is not a hard process. You can delete the program either manually, or automatically, depending on your own preferences. If you decide to uninstall the application manually, you should follow the bellow-provided instructions.

Though, even if you have completed the manual removal process, you still have to run a full scan of your PC to identify any registry leftovers or temporary files. You can do this by installing a legitimate antimalware tool which will locate and delete all the existing threats on the machine. In addition, the security software will keep your system clean and protected at all times.
