I’m sure this won’t be the case for long, Microsoft tend to be good about addressing things like this.
Fellow MVP Sandi Hardmeier has put out a very detailed post about the problem, I suggest you read about it there. It does raise some interesting questions. Not least, how are we supposed to protect ourselves against these things? I think her suggestion about making sure that you close unexpected windows using the ‘x’ in the corner is a good one. And making sure that you have firewalls and virus checkers is an absolute must. Using the ‘hosts file’ protection against this particular problem will help too.
