A new adware software, called “eFast Browser” works by installing and running itself in place of Google Chrome.
eFast is based on Google’s Chromium open-source software, so maintains the look and feel of Google Chrome at first glance, tricking users into believing that they are using the original Chrome browser.
The adware does all kinds of malicious activities that we have seen quite often over the years:
- Generates pop-up, coupon, pop-under and other similar ads on your screen
- Placing other advertisements into your web pages
- Redirects you to malicious websites containing bogus contents
- Tracking your movements on the web to help nefarious marketers send more crap your way to generating revenue
Therefore, having eFast Browser installed on your machine may lead to serious privacy issues or even identity theft.
