ZenoSearch, also known as Zeno Browser Enhancer, is an adware application that shows undesirable commercial pop-up advertisements based on keywords that the user enters into popular Internet search engines such as Google, Yahoo, MSN, Lycos and others. The threat doesn't carry any destructive payload. ZenoSearch must be manually installed. It automatically runs on every Windows startup.
