Zapp is adware created to probably show pop-up ads for commercial purposes. Once installed on the PC, Zapp may add an unwanted Web browser extension which is used for displaying random pop-up advertisements and messages. Zapp may spread and enter the PC bundled with free software that the computer users may have downloaded and installed from questionable download websites. If pop-up advertisements of Zapp are displayed on the computer, this may indicate that the PC has been affected by this adware. Zapp may double underline certain words on a website, and when the computer user hovers over them, 'Ads by Zapp' may be shown. Zapp's ads may be random or associated with the PC user's browsing habits and, if clicked, may reroute computer users to suspicious websites.
