Epicunitscan.info malware: remove NETWORK_FAILED error in Chrome, Firefox and IE

The browsing problem to be dissected in this posting isn’t new, the early reports about it dating back to mid-2014. Unfortunately, not much has changed ever since. The gist of the issue is as follows: when trying to install a new browser extension or update one currently installed, people get a popup saying, “An error has occurred. NETWORK_FAILED”. Some basic research reveals that the web browser is trying to reach a malicious https://epicunitscan.info/00service/update2/crx URL in these cases.

What is Epicunitscan.info?

The ongoing discussion of Epicunitscan.info boils down to browser troubleshooting where users are unable to get new add-ons and update the extensions already in use. This is a fairly complex instance of browser hijacking that intercepts web traffic, collects victims’ sensitive personal information (SPI) and prevents them from customizing their Internet surfing routine. It is a cross-browser infection, so it affects Chrome, Firefox, Internet Explorer and possibly other popular web navigation clients alike. With this perpetrating code inside a computer, it isn’t possible to install and get new versions of browser extensions. The target browser keeps returning “An error has occurred. NETWORK_FAILED” dialog suggesting a choice between two options – Reload or Close.

This change isn’t perceptible to the naked eye, but it does cause a number of adverse effects. Along with the above-mentioned inability to work with browser extensions properly, the victim will also be experiencing recurrent redirects of their Internet traffic.
