This killed my computer! NIS 2011 detected the virus as WS.Reputation.1! After I copied it to system32, UAC got killed and I had to do a system restore! DO NOT DOWNLOAD!

Did you take ownership before proceeding?
Impossible! I have McAfee and everything went well!
Moreover, the screenshot given above is of my screen itself.

Yes I took ownership, renamed the original authui.dll to authui.dll.backup and copied the file to my system32 folder. I think this might have been because Norton did something to the file. But I don’t want to try again.

Nathan, you DO realise he did not write to rename it to authui.dll.backup butto authui-backup.dll right?

And before you say anything, the .backup file extension IS a real extension.
