CouponChaser virus (Ads by Coupon Chaser)
The CouponChaser virus (also found as Coupon Chaser virus or Ads by CouponChaser; though not technically a computer virus) is potential malware categorized as adware and a browser hijacker that installs to a Microsoft Windows computer system and attaches to Google Chrome, Mozilla Firefox, and Microsoft Internet Explorer as a browser add-on, browser helper object (BHO), and extension with or without user consent.
Once CouponChaser malware is installed, it will begin to replace existing internet browser settings and displays unwanted pop-up advertisements, in-text ads, banner ads, and especially drop-down coupons ads on popular online retail websites including walmart.com, ebay, and others.
CouponChaser adware will attempt to display targeted coupons and offers for searched items or currently viewed products on retail websites by displaying a drop down tab and menu that can be identified by text that says the user has a numerical amount of coupons. The advertisements may drop down from the top right of the open internet browser window in a blue drop-down list that contains links to coupons. Once clicked a coupon may be applied to the visited webpage.
The CouponChaser pop-ups can be identified by a blue tab at the top browser window, the blue advertisements, as well as banners and skyscrapers.
Once a program that is used to assist in displaying CouponChaser advertisements is installed it will begin to change Microsoft Windows start-up settings and internet browser settings. Furthermore unwanted applications used to promote CouponChaser advertisements may violate user privacy by collecting and distributing sensitive user information and ruin a computer’s functionality and internet browsing experience (often associated with unwanted browser redirections and changed homepage settings).
CouponChaser malware and third-party items have also been reported to submit collected user information to third-party marketing and mailing lists without user consent. Some users have reported unwanted email spam, junk mail, and have even complained of unwanted telephone calls from telemarketers concerning their recent browser activity and history.
CouponChaser is also stubborn to uninstall and will make users reboot their systems and/or enter a verification code before the adware can be removed properly.
