What is Quick Converter?

The Malwarebytes research team has determined that Quick Converter is a search 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.

How do I know if my computer is affected by Quick Converter?

You may see this entry in your list of installed Chrome extensions:

and this changed setting:

How did Quick Converter get on my computer?

Browser hijackers use different methods for distributing themselves. This particular one was downloaded from the webstore:

Our program Malwarebytes can detect and remove this potentially unwanted program.

  • 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.
