Remove AddonJet “Virus” from Chrome/Firefox

I wrote this article to help you remove AddonJet. This AddonJet removal guide is working for Chrome, Firefox and Internet Explorer.

AddonJet is a program, designated for online advertisers. The utility enables developers to monetize their addons and toolbars by adding a 3-line snippet of code to them. AddonJet helps advertisers raise proceeds by delivering coupon notifications, displaying banners, contextual, video and in-text ads to users’ screens. Another function of the tool is to make data analysis. AddonJet implements a tracking code and collects information from users’ browsers. The concept of AddonJet hints that the program is adware. This is the conclusion security specialists have made.

What threats does AddonJet expose users to?

AddonJet generates advertisements to promote third party content. The majority of the ads are related to shopping deals. The shady tool lists bargain offers for a wide variety of items. The product palette consists of garments, accessories, technological devices, household appliances, sports gear, furniture, decorative elements, games, toys and many others. The offers the adware suggests may be good, but they are not confirmed to be legitimate. The advertisements could redirect you to corrupted websites, containing malware.

The developers of AddonJet do not target end users as a customer group. They have created the tool to collaborate with online advertisers. For this reason, people’s security is not a prime concern. The only benefit from computer users is their willingness to follow the ads. The more windows the users click on, the more proceeds the adware’s owners would make. AddonJet utilizes the pay-per-click system to make revenue. The owners of the secluded program receive commissions for every time a user clicks on a supported link.

The data analysis function of AddonJet leads to another potential threat. As per description, this task is aimed at studying online behavior and drawing conclusions about the preferences of targeted groups. Gathering information can be a privacy violation, if the adware records personal and financial details. To avoid legal repercussions, the owners of AddonJet have published limitation of liability statements in the terms and conditions and privacy policy sections. The program is a product of Sierra Labs, Inc. The company has opted out of responsibility for all security issues, resulting from the use of the tool.

How did AddonJet get installed to your computer?

The official website of AddonJet,, does not provide a download link for the utility. The rogue program is only distributed through unofficial sources. The distribution method the adware uses most often is called bundling. The furtive tool latches onto other programs and tries to get installed in parallel with them. You should read the terms and conditions of the software you intend to add to your system. This is where the option for extra tools would be listed.

Spam emails are the other way in for the adware. The executable of AddonJet can be hidden behind a file, attached to an email message. Opening the attachment would initiate the download and install of the clandestine program. Spammers often make use of macros, scripts and other malicious files when spreading malware. You need to be certain an email is reliable before proceeding to open attachments from it.
