When this system boots up, I get a dialog stating that "An unauthorized change was made to your license." The only options I have are to Validate Online or Close (close returns me to the login screen) I attempt to Validate online, and am told there was either an unauthorized change or a software program on the computer is not currently compatible with Vista.

What I've done so far:

I've gone through the recommendations listed (Restarting the Software Licensing service and running Disk Cleanup)

Uninstalled PCDoctor and a few other non-essential utilities

ran Malwarebytes, Spybot, and ComboFix while booted in Safe Mode (found and fixed errors, malware, etc..)

I am STILL at the same place. Somewhere along the line, I noticed "Rootkit: TDSS" but all the instructions for removing it that I have found depend on booting into normal mode.

I really need someone to help me through this issue please.

I found this Microsoft Support Article: http://support.microsoft.com/kb/931699

If you've done the uninstallation of any incompatible programs (and tried a system restore from before this problem started?) then it would seem like it could be malware causing this issue.

I noticed "Rootkit: TDSS"

+1 for malware.

You might want to post in this forum: http://www.bleepingcomputer.com/forums/f/103/am-i-infected-what-do-i-do/ to see if someone can help you out. Start a new topic and describe the issue and the steps you have been through - also say about the Rootkit issue.


If I have been helping you and I do not reply within 48hours, feel free to send me a PM.
