I receive the exact same error message and mine is a clean install to a reformatted hard drive so it is NOT virus related. I made no customizations and everything else seems to function just fine but I am unable to edit the icons that appear next to each username I have set up on the computer.

As to Colors problem, you can get around it by right-clicking on "My Computer" and choosing "Manage" (or click Start/Control Panel/Performance and Maintenance/Administrative Tools/Computer Management) and go into "Local Users and Groups/Users". From here you can add and delete users, change passwords and user accounts.
