Brief Description 

    

Browsezilla is offered as a web browser. However, it is detected as adware due to the following reasons:

  • It is automatically downloaded to the computer when carrying out a search using it, without asking for user permission.
  • It installs itself without user's explicit permission and knowledge.
  • It does not display an EULA (End User License Agreement) during its installation.
  • One of its components downloads and runs automatically a file without asking for user permission.
  • It offers links to adult content without clearly asking for user consent.

Browsezilla can be voluntarily downloaded when visiting certain websites for adults, and from the website belonging to the company that has developed it.

 

Note 1: although a former version of Browsezilla downloaded a copy of the adware PicsPlace to the affected computer, a newer version has been released, which does not carry out this action.

Note 2: from version 2.0.1 on, Browsezilla has modified its behavior, and therefore newer versions are no longer detected as adware. However, previous versions, which carry out the actions described, are still detected, in order to protect our clients appropriately.
