What is Dealnj?

Dealnj is a dubious browser plug-ing that supposedly helps to save time and money when shopping online - "Dealnj is a light-weight browser extension that simply shows you better deals before you shop online, and save you money!" These false claims often trick users into believing that Dealnj is a legitimate app, however, due to rogue behavior, Dealnj is categorized as a potentially unwanted adware-type program (PUP).

Dealnj infiltrates systems without users’ permission, generates intrusive online advertisements, and tracks Internet browsing activity.

Dealnj adware

Dealnj employs a 'virtual layer' to display pop-up, coupon, banner and other similar advertisements. These often conceal underlying content, thereby significantly diminishing the Internet browsing experience. In addition, some lead to malicious websites - clicking them can lead to further high-risk adware or malware infections.

In addition, Dealnj continually monitors browsing activity by gathering IP addresses, websites visited, pages viewed, and other similar Internet browsing-related information. It is highly probable that this collected data will contain personal details that developers of Dealnj share with third parties who misuse personal data to generate revenue.

Thus, the presence of Dealnj on your system can lead to serious privacy issues or even identity theft. You are strongly advised to uninstall this PUP immediately.

Research shows that there are hundreds of adware-type programs offering identical functionality. ClashOfCash, TidyNetwork, and Offerz4U are just some examples from a long list. Although all seem legitimate, none provide the functionality promised. Adware is designed only to generate revenue for the developers.

Rather than enabling the functionality promised, Dealnj, and other similar apps, deliver intrusive online advertisements and collect personally identifiable information (PII).

How did Dealnj install on my computer?

This PUP has an official download website, however, many users install this application inadvertently. This is due to deceptive software marketing method called 'bundling' - stealth installation of potentially unwanted programs with regular software/apps.

Users commonly do not pay enough attention during the download and installation processes - aware of this, developers conceal bogus software within the 'Custom/Advanced' settings. Thus, by rushing these processes, users expose their systems to risk of various infections and compromise their privacy.

How to avoid installation of potentially unwanted applications?

The key to computer safety is caution. Never rush the download or installation processes. Closely analyze each step using the 'Custom/Advanced' settings. All additionally-included programs should be cancelled and offers to download or install third party apps, declined.
