Ask Toolbar

What is Ask Toolbar?

The Ask Toolbar is a web browser extension and toolbar that delivers contextual based advertising as well as modify the user's web browser home and search pages to provide advertising and search. The software is typically defined as a potentially unwanted application by various malware vendors.

What the browser extension does:
- Changes the default search engine.
- Changes the default browser home page.
- Adds search from the address bar.
- Adds alternative redirection "page not found" and DNS errors.
- Displays contextual advertising by injecting banner and text ads.
- Prevents other applications from changing the toolbar settings.

It is often installed during the installation of other software. Ask.com has entered into partnerships with some software security vendors, whereby they are paid to distribute the toolbar alongside their software. When you use the Toolbar to submit a query, the Toolbar forwards such query information to Ask servers. Ask.com uses this information to process your web search requests and to return a search results page to you.
