Short bio

Adware.BrowserAssistant is Malwarebytes’ detection name for a family of adware signed by Astral Media Inc. and aimed at Windows systems.


Users will typically see advertisements that are not coming from the website they are visiting.

Type and source of infection

Adware is typically a standalone program which displays adverts to the end-user in a variety of forms, including:

inside the program itself via pop-ups and pop-unders, in or outside the browser slide-in adverts launching a browser window inserted adverts, or otherwise altered website content

Adware has traditionally been spread through the affiliate model, where individuals or supposed business entities sign up with the adware vendor then distribute it via websites, bundled products, and other offers.
