Just because this is something that should get out there, a while back some hackers broke into peoples computer and did some DNS look up changes to victoms computers. See http://www.fbi.gov/news/stories/2011/november/malware_110911 for info on how to check your computer. If you use IE you really need to check to make sure you are safe (I don’t use IE used Firefox at that time, but use Crome now, but still best to check and I did, I was not affected)
Just re posting this as it is something that does need to get out there.
