What is BuyFast?

BuyFast does not have a legitimate description from the publisher; However, programs and browser add-ons and extensions similar to it are often promoted by third-party freeware and download managers as a bundled web shopping assistant or web utility program that help help internet users find coupons and deals.

Potential BuyFast malware generates deceptive and intrusive pop-up ads across Chrome, Firefox, Internet Explorer, and Safari. Ads by BuyFast  are defined as ‘targeted’ ads because they use your personal browsing information (including all your data on the websites you visit) to produce advertisements it feels you are most likely to click on. The adware basically ‘targets’ you based off your current and past browsing habits.

BuyFast 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. The internet security community strongly recommends that you remove BuyFast if you find it installed on your machine or attached to your internet browser as a browser add-on or extension and use reputable Antivirus or Anti-Malware software to eradicate any existing malicious files.
