Ads by DealDay

What is DealDay?

DealDay is a potentially unwanted program (PUP) and adware. There are a number of reasons for these negative associations. Firstly, DealDay claims to display special deals/discounts, coupons, and enable comparison shopping to save time and money while shopping online.

Therefore, some users assume that DealDay is a legitimate and useful app, and go on to accept installation. This software is often distributed ('bundled') with other free software.

After infiltrating the system, DealDay behaves as a regular adware app - tracking Internet browsing activity and displaying various types of intrusive online advertisements. Furthermore, the presence of DealDay adware on your system might affect your browser and computer performance.

DealDay uses the 'Pay Per Click' (PPC) advertising model to monetize the displayed adverts - when users click banner, pop-up, coupon, and other ads, the developers of this PUP receive payments. Many users are unaware that these generated advertisements do not originate from the websites visited and provide no real use for the user.

In fact, they overlay websites with ads, making reading the underlying content difficult. When clicked, the ads generated by DealDay adware may redirect to commercial websites such as online stores. Although these ads may seem harmless, they are misleading - some redirect to infectious websites, thereby causing high-risk computer infections.

In addition, DealDay collects various types of information by continually monitoring users' Internet browsing activity. Websites visited, pages viewed, search queries entered, Internet Protocol (IP) addresses, and other information types are gathered and stored on a remote server.

Research shows that this collected information is later sold to third parties (another means to generate revenue).

Third parties receiving this information may be cyber criminals, and since the collected data may include personally identifiable information (for example, PayPal and other financial services related to the website's account), this may lead to serious privacy issues or even identity theft.

If you concerned of the potential threat posed by DealDay adware, uninstall this PUP from your system immediately.

Adware-type applications often have similar or identical characteristics - they are designed to record personally identifiable information and display intrusive online advertisements. Furthermore, most are distributed using the bundling method. Although they promise to enable features to significantly improve the Internet browsing experience, none have any real value.

The purpose of WikiBrowser, TomorrowGames, On Stage, and other adware-type apps (including DealDay) is to generate revenue for the developers. Therefore, never install unrecognised, bundled software.

Today, downloading software from freeware download websites is popular, however, be aware that these sites monetize their traffic and free services via small programs called 'download clients' (also called 'installers', 'download managers', 'download tools', etc.).

When downloading free software from download websites such as downloads.com, softonic.com, and soft32.com, users are forced to use download clients, which supposedly 'simplify and speed-up' the download procedure. Despite these claims, download clients are used simply to distribute third party applications (potentially rogue) together with the chosen software.

How did DealDay install on my computer?

The bundling method is a deceptive software marketing technique, which allows developers to stealthily install additional programs together with the chosen software. Adware-type apps are often bundled with free software downloadable on freeware download websites.

Research shows that many users do not pay enough attention when downloading and installing software - they skip most of the steps and fail to read the information (if actually provided in the first place). In some instances, rogue applications are concealed and the user is not able to opt-out.

These apps are often hidden within the 'Custom' or 'Advanced' settings, and since many users skip this section, they inadvertently install apps such as DealDay. Developers do not properly disclose installation, since they aim to stealthily install as many rogue apps as possible.

In conclusion, lack of attention by users during download and installation of free software is the main cause of computer infections.

How to avoid installation of potentially unwanted applications?

If freeware download websites enforce the use of download managers, the safest way to download is from the official websites only. Some freeware download sites provide a direct download link, which is also a safe choice. If you must use a download manager, check each step of the procedure to ensure that no additional software is included.

Software installation should be performed using the 'Custom' or 'Advanced' options - this will reveal any third party software listed for installation and allow you to cancel it, thus preventing computer exposer to risk of infection.
