Webext is an adware application, which shows unsolicited commercial pop-up advertisements based on keywords that it detects in the text, which the user enters into the web browser's windows. The threat regularly contacts a predetermined remote server in order to update its configuration settings. Webext must be manually installed. It works as an Internet Explorer add-on and therefore runs every time the user launches the web browser.
