My husband wrote this up for me because I have no idea exactly what it is about. I did, however, go to DCWG.org to make sure my computer was ok.
This is the story:
Over a year ago, the FBI discovered malicious software that redirected over a half-million computers through a specific DNS server. (A DNS server is used to resolve the meaning of web addresses you type into your browser.)
This malicious server captured information and began to use your computer without your knowledge. Rather than knocking many computers off the internet, the FBI substituted a “Clean” DNS server for the malicious server. Beginning Monday July 9, the FBI will shutdown the “Clean” server and anyone still infected will suddenly not be able to get to the internet.
To fix the problem the person will probably need to work with their internet provider to enter the correct DNS information.
To avoid the problem many places have be publicizing a website that will check your current DNS location.
