The DNSChanger virus: At the outset it appears to be on par with doomsday Y2K or Conficker worm hysteria. But it’s not. The Internet itself is not going to implode. In fact, the explanation is pretty simple and the fix can be applied in a matter of minutes. That said, come Monday, many users with the DNSChanger virus plaguing their computers will be kicked offline until the nasty bug is removed.
