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 read through and done the recommendations listed (Restarting the Software Licensing service and running Disk Cleanup)

Read through and done what was suggested by Microsoft at: http://support.microsoft.com/kb/931699

Uninstalled PC Spyware Doctor and a few other non-essential utilities

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

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. At this time I can boot into all modes of SAFE MODE, but unable to get to desktop in a normal boot.

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