On my system a user named bye was automatically created after a system reboot. After system booted, my network DNS Primary IP and alternate IP were changed automatically to

  • DNS Primary:
  • Alterative:

I can't work on the internet with the original IP of my LAN connection.

Please guide me how I can remove the user bye and this problem without reinstalling the operating system.

what did that have to do with lsass.exe? Do you have a working anti-virus/anti-malware software? Also, see this question for more details. – slhck May 14 '11 at 8:00
For the record, these two addresses belong to Google Public DNS project, and are safe to use. – grawity May 14 '11 at 14:21
