The malware backdoor in this story is quite intriguing. They are targeting specific companies (Samsung, Akamai, Cisco, Microsoft amongst them) and only attempting the second level attack if they are detecting they are being installed there.
The advice mentioned in the article is that anyone who installed the software on their system should REFORMAT THEIR DRIVE. Quite an extreme recommendation. My suggestion - stop using Windows.

I am actually not that surprised with Microsoft’s behaviour on this. Forcing an upgrade onto people without consent. In fact, it was using malware-like tactics to make you (or persuade you) to upgrade.
