I don't see any other 'foolproof' way of removing all traces.
We never recommend scanning through the registry to remove all traces. That can cause no-end of problems.
So, first of all use the Office 2010 CD to uninstall it, then reboot afterwards. If that doesn't do it, use System Restore to restore back to a time before it was ever installed.
Wouldn't it be better to tackle the virus?
Hello, I recently encountered a nasty problems with Microsoft Office 2010 because of a virus. Therefore I must remove Office 2010 completely.
How do I remove EVERY SINGLE TRACE of Office 2010 (including EVERY registry entry, file, information, activation history, etc.)?
P.S.: Basically, the computer should exist in a state as if Office 2010 was never installed.
