How to remove S3.amazonaws.com from Mac

Sharing is caring!

What is S3.amazonaws.com?

S3.amazonaws.com is an ad-supported domain that may start to appear in your browser from time to time. Unfortunately, this activity indicates that your system is infected with adware. As a rule, S3.amazonaws.com gets on users’ Macbooks after users get redirected to rogue sites claiming that an Adobe Flash Player update needs to be installed, and end up installing it. Other ways for adware to end up on users’ machines are users installing free software and not opting out of extra programs that are also offered for installation, or users opening files downloaded from shady websites.

This is a description of the problem of one of the users:

The issue starts to appear on some websites, where when the site starts to load, the original ads are loaded and then almost immediately they are covered up by other ads. After some time audio starts playing and pop-ups appear with messages like “congratulations, we want to make you a millionaire” or something similar. Additionally, when on the main page I am scrolling and there is a .gif post it automatically redirects me to the post page.

Having S3.amazonaws.com adware installed on your device is not dangerous but it significantly reduces browsing and system performance as a whole. Hence, we advise you to remove S3.amazonaws.com as soon as you can. To do so, follow our step-by-step guide.
