Ezula (sometimes spelled "eZula") is a form of adware installed as part of a browser helper object (BHO). Without the user's permission, ezula communicates with a remote server and displays context-based advertisements to the individual.
Ezula contains no dangerous viruses but can slow a user's browser and has to be manually installed by the user. As it comes as part of a BHO, it may appear as an optional third-party add-on during the install process. The program adds advertising links to keywords on a Web page, and when clicked on, it directs the user to a third-party website — usually unrelated to what they were originally searching for. The program automatically begins on a Windows start-up and can remotely update itself via the Internet without user consent. It has been reported to come as part of a program named TopText or Surf+.
Adware refers to programs that are made to display advertisements on your computer. They can redirect search request to advertising websites and can collect data about your browsing habits, so that they can provide tailored adverts for the user. When it collects information without the user's permission or without notifying the user, the program is considered to be malicious software.
To avoid adware and programs similar to ezula, users can set up afirewall. This protects the computer and notifies users of any third-party or unauthorized software trying to access it. Users can also try changing Web browsers. For a more comprehensive solution, users can install advanced Internet security software to protect their home computers.
