What is YunPanSer?

The Malwarebytes research team has determined that YunPanSer 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 hijacks browser shortcuts.

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

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

and these warnings during install:

this type of change to your browser shortcuts:

and you will see these icons in your startmenu and on your desktop:

How did YunPanSer get on my computer?

Browser hijackers use different methods for distributing themselves. This particular one was offered as Baidu Cloud Search.

How do I remove YunPanSer?

Our program Malwarebytes can detect and remove this potentially unwanted program.
  • Please download Malwarebytes to your desktop.
  • Double-click mb3-setup-consumer-{version}.exe and follow the prompts to install the program.
  • Then click Finish.
  • Once the program has fully updated, select Scan Now on the Dashboard. Or select the Threat Scan from the Scan menu.
  • If another update of the definitions is available, it will be implemented before the rest of the scanning procedure.
  • 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 YunPanSer?
  • No, Malwarebytes removes YunPanSer completely.
  • The shortcut called 百度网盘种子综合搜索器 on the desktop can be deleted if it belonged to the rogue.
How would the full version of Malwarebytes 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 would have protected you against the YunPanSer hijacker. It would have warned you before the application could install itself, giving you a chance to stop it before it became too late.
