Abigail, I’ve removed your contact details from this post as publishing them here might expose you to all sorts of invasions of privacy. I’m afraid that even if I lived in the US I wouldn’t be able to get a letter to you in time to avoid this problem, if it in fact affects you, which is only possible if you have, in fact, been infected at some point by this particular malware, and even then isn’t an inevitable result. (The number of people who will be affected is probably in tens or even hundreds of thousands, but that does mean that there are many, many more people who won’t be affected.) In any case, it sounds to me as if what you need is information clearly expressed and specifically based on your own system, not more detail. As researchers/bloggers, we’re not usually in the best position to give one-to-one support, but I can give you a little very generic advice.

If you have good anti-virus installed and it’s working properly, it’s very unlikely that you were ever infected. I can’t advise you on how to check whatever anti-virus you do use, but the vendor or its distributor should be able to advise you on that, and may even help you check your DNS settings. If that’s a problem (or even if you just want confirmation that you aren’t infected) you could try the ESET online scanner: just follow the directions at http://www.eset.com/us/online-scanner/. If you don’t have the infection, you probably don’t have the DNS problem.

The real problem for people whose systems have been infected by DNSchanger is that even if the infection is removed, their DNS settings may not have been fixed, and that means that their connection to the internet is partly dependent on a computer controlled by the FBI, which is about to shut it down. If you’re unable to follow the instructions in Cameron’s blog at http://blog.eset.com/2012/05/31/dnschanger-%e2%80%98temporary%e2%80%99-dns-servers-going-dark-soon-how-to-check-your-computer on how to check DNS settings, I really think you’d be best off getting help locally or from one of your friends or relations. Even if it means paying a technician, it might be worth doing that for the reassurance. I’d certainly suggest that you do so if you have reason to think that you _have_ been infected by DNSchanger.

Sorry I can’t offer more specific advice. If I lived in your neighbourhood, I’d offer to pop round, but I’m afraid I don’t even live in the US (I assume that’s where you live).
