Cleaning a compromised system

Personal data backup (which none should be considered 100% reliable at this point) then format the HARD disk and do a clean install of Windows. Please note that a repair installation (upgrade AKA on-site) will NOT fix it!

HOW to do a clean install of Vista: section "If you want to reinstall Windows Vista by running a new installation...". "ofhttp://windows.microsoft.com/en-us/windows-vista/Installing-and-reinstalling-Windows-Vista

Once installed the clean, you will have the equivalent of a "new computer" in order to take care of everything on the next page before connecting the machine to the internet or one local network (i.e. other computers) otherwise and before using a flash drive or the SD card that is not brand new, or has not been freshly formatted:

You MUST uninstall the trial for free and download/run the appropriate removal tool before installing updates, Service Packs, Windows or the IE upgradesand before to install the new anti-virus application.

If these procedures look too complex - and there is no shame in admitting this isn't your cup of tea - the owner must take the machine to a local, reputable and stand-alone computer (i.e., not BigBoxStoreUSA or Geek Squad) repair shop.

Wish I had better news for you (and owner). Good luck.
