Victim: My laptop computer (2009 Sony VAIO VGN-FW560F) has been infected with this, along with a slew of other adware and alike, since yesterday. Caught this **** while downloading some mods for a game (or so I thought).
I'm currently running Windows 10 and Windows defender. Windows defender did a decent job of removing most of the malware and other things except this one Trojan.
