Removal instructions for OZIP

Recommended Posts

What is OZIP?

The Malwarebytes research team has determined that OZIP is a browser hijacker. These so-called "hijackers" manipulate your browser(s), for example to change your startpage or searchscopes, so that the affected browser visits their site or one of their choice. This one also displays advertisements.

How do I know if my computer is affected by OZIP?

You may see this entry in your list of installed software:

How did OZIP get on my computer?

Browser hijackers use different methods for distributing themselves. This particular one was bundled with other software.

How do I remove OZIP?

Our program Malwarebytes Anti-Malware can detect and remove this potentially unwanted program.

It is advisable however to run the built-in uninstaller first (see first screenshot).

  • Please download Malwarebytes Anti-Malware to your desktop.
  • Double-click mbam-setup-version.exe and follow the prompts to install the program.
  • At the end, be sure a check-mark is placed next to the following:
    • Enable free trial of Malwarebytes Anti-Malware Premium
    • Launch Malwarebytes Anti-Malware
  • Then click Finish.
  • If an update is found, you will be prompted to download and install the latest version.
  • Once the program has loaded, select Scan Now. Or select the Threat Scan from the Scan menu.
  • When the scan is complete, make sure that all Threats are selected, and click Remove Selected.
  • Restart your computer when prompted to do so.
Is there anything else I need to do to get rid of OZIP?
  • No, Malwarebytes' Anti-Malware removes OZIP completely.
  • If you are using Chrome, you may have to remove the Extension manually under Tools > Settings > Extensions. Remove the checkmark and click on the bin behind the OZIP entry.
How would the full version of Malwarebytes Anti-Malware help protect me?

We hope our application and this guide have helped you eradicate this hijacker.

As you can see below the full version of Malwarebytes Anti-Malware would have protected you against the OZIP hijacker. It would have warned you before the application could install itself, giving you a chance to stop it before it became too late.
