CostMin

CostMin is a web browser extension that functions as adware, redirecting web searches and injecting advertising. When used on Internet Explorer, the program operates as a Browser Helper Object. The add-in is capable of hijacking advertising on unrelated websites, as well as inserting its own advertising in the form of contextual link ads, banner ads, popups, and pop-overs, including on established ad serving sites. The malware is commonly distributed alongside unwanted third-party applications and through web browser vulnerabilities. While the program is equipped with an uninstaller and can be found in the Windows Add/Remove Programs, complete removal may prove challenging and may require the use of an anti-malware product. The Plugin is supported by third-party advertising, and upon downloading it, users will encounter various types of advertisements while browsing the internet, including sponsored links, traditional display advertisements (such as banner ads, "pop-unders," and interstitial ads), coupons, and video targeted ads. Additionally, the plugin may display sponsored links in the form of in-text advertising, and in response to keyword searches made through search engines like Google, Bing, and others.
