BTW, as a computer guy you should know that Windows of today is based on VMS.
My guess is that the original poster is not running a modern Windows variant or did the click and hope for the best method of implementation.
I do not buy this widespread virus spread we saw in the past (which was a problem, I agree).
Later, doing some Unix development I was surprised to see VMS code, lifted from fiche probably, the the Unix kernel. Unix/Linux was and is a grad school project. Apache works because it doesn't have to change. Macs work because Apple has always taken the no one but Apple approach. That is why it will never be used extensively in business, except the publishing business. More credit to Apple's business model. They get all sorts of free publicity and have a committed clientele happy to pay fifty percent more for a limited machine.
This trojan looks nasty, but I've never had a trojan, and neither have most people. A firewall will prevent reassignment of DNS addresses. Current antivirus definitions will identify most trojans. Microsoft gives away pretty decent antimalware tools to legitimate customers. Defender and whatever they named the antivirus product seem fine. My dozen systems run Microsoft and BitDefender. I always use Defender. Being a bigot of any platform is an old story. Unix has been taking over for thirty five years now, but Dave Cutler's work, RSX-11, ELN, VMS, Windows after NT, is real engineering excellence. Some of the imitators look promising, such as Mono. Mono will allow the proliferation of truly machine independent tools, based upon Microsoft innovation, a machine independent Intermediate Language with support for over sixty procedural languages. Mono will promote the migration of .Net to markets outside of Microsoft's business domain.
