Some Windows 10 users may experience a problem whereby their Microsoft Edge browser homepage switches from the standard MSN (or other website they have chosen) and redirect to a site called Duba.
When this occurs, it means that the user has been exposed to a browser hijacker that could have been downloaded alongside a piece of software, or accidentally through a fraudulent email. A browser hijacker is a piece of computer malware that changes your homepage and search engine, and in this instance, it changes your search engine to www.duba.com.
While this virus isn’t technically malicious, and won’t steal any of your personal data, it will be extremely difficult to remove for novice Windows users.
Using some popular freeware, however, it is possible to remove the Duba virus and set your homepage and default search engine back to its original settings.
