Deal Dropper Virus

What is Deal Dropper?

Created by Engaging Apps, Deal Dropper is a browser add-on claiming to save time and money by enabling coupons, comparison shopping, displaying discounts/special offers available on shopping websites, and providing other similar functionality. Although this browser add-on may seem legitimate and useful, be aware that it is considered to be adware.

Deal Dropper employs a deceptive software marketing method called 'bundling' to install on browsers (Internet Explorer, Google Chrome, and Mozilla Firefox) without users' consent.

Following successful infiltration, Deal Dropper generates various intrusive online advertisements including banner, interstitial, sponsored link, text-link, pop-up, and targeted video ads. There is a high probability that clicking these ads will lead to high-risk adware or malware infections.

In addition, users' Internet browsing activity is continually monitored, since this rogue browser extension records various software and hardware information such as search queries entered, URLs visited, pages viewed, cookies, IP addresses, geo-locations, unique identifier numbers, and other similar details, which may be personally identifiable.

This behavior may result in serious privacy issues or even identity theft, and therefore, users are advised to uninstall Deal Dropper from their Internet browsers. During research, this potentially unwanted application was distributed via free software 'download managers' (on freeware download websites) and fake downloads (Java updates, browser updates, etc.)

Deal Dropper is similar to other rogue browser plug-ins (for example, Coupon Lasso, Savings Season, and DropIntoDeals), which claim to improve users' Internet browsing experience by enabling certain functions. Neither Deal Dropper, nor any of these other browser plug-ins add any real value for users.

Commonly, users inadvertently install adware such as Deal Dropper during the download of free software via download managers on freeware download websites (for example, download.com, soft32.com, and softonic.com)

Most of these websites employ small programs called 'download clients' to monetize their free services by offering installation of promoted 'legitimate' browser add-ons together with the chosen free software. Thus, careless download and installation of free software usually results in adware or malware infections.

This situation can be prevented by paying close attention when downloading freeware and never accepting installation of any additional programs offered. If you are installing downloaded software, select the 'Custom' or 'Advanced' installation options - this will reveal any hidden applications listed for installation and allow you to opt-out.

Internet users who have already installed Deal Dropper and observe "Ads by Deal Dropper" advertisements when surfing the Internet, should follow this removal guide to eliminate Deal Dropper adware from their Internet browsers.
