What is Companion?

“Companion” and adware like it are usually promoted as free web shopping utilities that provide coupons and deals for the products you view on retail websites and search for online. There are a variety of adware type programs and browser plugins that use the word Companion in their title.

Companion adware generates pop-up ads across Chrome, Firefox, Internet Explorer, and Safari.

The adware basically ‘targets’ you and your current and past browsing habits.

Companion adware is not technically defined as a computer virus but this adware is still a threat to your privacy and can be the sign of a severe malware infection since it is known to bundle with other unwanted programs and malware.
