How to uninstall SmartTransaction app/extension from Mac (Virus removal guide)

What is SmartTransaction

According to security professionals, SmartTransaction is an adware application that targets Apple computers. Adware’s basic purpose is to display ads. These ads are often displayed as advertising links, popups or various offers and deals, push notifications and even fake alerts. Clicks on the ads produce a monetary payoff for the adware makers. Adware can work like Spyware, since it sends sensitive information such as searches and trends to advertisers.

Another reason why you need to get rid of SmartTransaction is its online data-tracking activity. It has the ability to collect lots of your user information (your ip address, what is a web-page you are viewing now, what you are looking for on the Internet, which links you are clicking), which can later transfer to third parties.

How does SmartTransaction get on your MAC OS

Adware spreads bundled with various free programs. This means that you need to be very careful when installing programs downloaded from the World Wide Web, even from well-known download sites. Be sure to read the Terms of Use and the Software license, select only the Manual, Advanced or Custom installation option, switch off all additional web browser extensions and software are offered to install.
